great buy, they are 99% sure to be merkel if it doesn't say Product of Valley under the logo..the only Grey's that were partial merkel were the 30th (Prod of Valley) so it would be very odd if they were not merkel
on the push shot, the reason it has never been an accepted winning shot at Majors from the 70s until today is because it is really really hard to square off (or angle back in a 7 motion like on the pull) a 1/2 finger long 9 out of 10 times over and over...i've shot the 1/2 finger long before but not over and over...I have seen palm roll shooters who can square off better but you lose some control, some finesse, when you move to a palm roll on the same man (meaning when you do a pull kick with a palm roll the long can be shot 1/2 finger, or even dead mean 9 out of 10)
the only person Ive seen shot a pretty consistent squared off long with the wrist only is Tony Spredeman but if you watch him shoot it, it becomes obvious how hard it is mechanically to make this happen which is another reason it has never been adopted as a primary tournament shot
it is strange too since so many of us find our first shot is a push when we just start out and don't know nothin...I did and I know many more players than I can count that started out the same
I personally think, and many will not agree, that the start speed, and overall speed, of a push is better than any of the pull options and that it is one of the more natural shots, if not THE most natural shots (of the inline options) on the table which is why I guess so many beginners end up choosing a push
Maybe it has to do with starting sort of like a sprinter, ready, set, and push off…I know for me, I felt that way coming from a background as a sprinter…who knows, it’s a shame though that the wrist just doesn’t work that way and when you are pushing or throwing the rod away from you, its so hard to get out ahead of the ball and come back where with a pull, that is almost natural
