this won't answer your stroke part of your question but it will answer the what/when do you shoot question...this is long, and is only about half of what I have, but take a few min to read through, Eric Dunn has written some good stuff on this subject...
Reading Defenses and Strategy (The Play Book)This following section by Eric Dunn, from 2 different posts but covering the same approach, is about reading defense and offensive approach with a rollover. However, what he covers is sound for any pinned shot (Euro Pin and Back Pin) and there are many principles that can be used with any shot. This is not a simplistic approach but it is sound, accurate, and articulately communicated.
Note: This material could be studied and used sort of in reverse when developing your defenses. how to read the D when shooting a rollover (Foosball Board)

I think its more important to learn different ways to read a defense over learning 'how' to read a defense. Yes i shoot a rollover. and yippeee I’m a pm.. I shoot it from a stand still, a stutter rock, and a full rock. Within each of these motions or stand still sets, I find it helps to be able to read differently. In its simplest terms, you can either shoot at a man (hoping it moves out of the way), or at a hole (hoping it remains open). There are many other ways as well, but these are the ones to start with.
AND you can either shoot man or hole the moment you see it open, or you can pre-read it.
Even if you learn a good way to read a defense, the better goalies are eventually going to figure you out, show you what you want to see, or show you something that makes you uncomfortable, and then you start to get blocked.
This is why it’s important to change how you are reading the defense often. I change how I am reading the defense mostly after 1 block.
I don’t let the defense dictate how I am reading the defense either. I think that's a mistake. I decide how I am shooting the ball before I even gain possession (yes it’s scripted - see other posts from me on that). Defenses are too good at showing you something, then changing it up at the exact right time - and it’s not a mistake - it’s planned.
If you get in the habit of
1. get ball
2. setup
3. read defense
4. decide how you want to shoot
5. wait for it
6. shoot
better defenses will figure out when you do #3, and be able to bait you for what they want you to shoot. I say screw that. I've already decided, I’m reading how I want, for the movement I want, and it’s probably different than what I did last time (if I got blocked). So I can shoot when I want. Sometimes quick shoot, sometimes wait - like others have said.
Shooting blind - with a slight adjustment isn’t bad either. The adjustment I would make is to not look at the defense for a number of seconds (I actually close my eyes - and count to some number), and then I open my eyes, and am effectively quick shooting (with a very quick read) on my own terms.
It might sound like a lot of thinking, and too many combinations to think of at once, that why I think it helps to script it. You can have a game plan that goes something like this:
I'm going to start off the game by shooting off a full rock - shooting at a man.
then if I get blocked, I’m going to switch to a full rock - shooting at a hole (this would be a natural progression, from man shooting, cause they are likely leaving holes open if you got blocked shooting at a man)
If you get blocked, to mix things up then you can do a quick shot -- by now you should have had a few attempts to read the defense when you were setting up the previous possessions, and have a good idea of what to shoot on the quick shot (i.e. what did the defense do when you started into your rock).
Then repeat. And keep shooting the same way until you get blocked (or you feel you got blocked, as apposed to missed or lucky block etc).
So to break it all down. Shoot man, shoot hole, quick shoot, repeat. Is one way you can mix things up enough to keep goalies guessing.
What hasn’t been talked about a lot is how one reads are given way.
If I've decided to shoot at a man this time, this is what I do anyways.
While I'm rocking, I'm simply watching the defense, for anything that seems repetitive. For me I just watch, and something comes to me - some others pick a man, and only watch that man, and again they are looking for something that appears to keep re-occurring... like maybe when the goalie man goes to the push side, he pauses, baits once (small twitch), then comes off.
Wait for the goalie to do that again, and wait for the bait, and shoot at that goalie. This is the thought process for a pre-read.
The thought process for a moment you see it shooting (still shooting man) might go something like this.
Read the defense to get a sense of which hole (push, pull, middle) is open more often than not. ok got it. looks like he's coming off push more (baiting lots on pull and strait).. ok next time he plants a man or waves a man across push, I’m shooting push.. wait wait wait.. ok bam.
This is single man reading.. there is also the concept of what i call image reading, where you take into account the position of both rods, and wait for the rods to appear back in that position, and shoot accordingly.. you can either shoot at the image (shooting hole), or you can shoot after the image (shooting man).
