well, the ball, rods, bearings, surface, men can all play a part in table speed...the bearings, balls, rods are all conistant (realitively speaking) even the men Brwn Mrbl up to the Grey Mrbl were the same
every so often, Tornado does something a little different in manufacturing the surface...below is a post from Ed Geer if I remember right...this doesn't really explain how the surfaces play different but it explains why surfaces change from time to time
to an average person, the changes mean nothing but to a serious player, they can really see the differences
the biggest differences have been in the Cherry...looks the same but it is for sure faster and there is no other explanation that can reason the change
the other is on the 30th Ann model...I think it is the darker green Ed mentions below...as time has gone on, I have heard more comments from every level player that they feel the 30th played better than any other...i have a friend with a 30th and his is probably my favorite Tornado of all time after he changed the men, handles, 5 hour tumbled ball, and new low profile bearings...it was great before, but those changes make it the best I have played on...good balance between speed and control
note, more speed means less control...control is created through friction and friction is the bane of speed
weight plays a role too but friction is the most obvious
get yourself a number of different balls, with various textures (super hard cheap soccer style balls to a Bonzini cork ball), and play with them a few minutes on the same Tornado table and you will see what i mean...even the difference between the old pink Tor ball and the new 5 hour tumbled ball is big but then throw a Warrior ball on the table and have some fun...big big difference
ED GEER...
There are 2 manufactures of custom high pressure Laminate that I know Tornado has used in the past, they are:
1. Wilson-Art
2. Pionite
The original 1981 spec for the surface was that of Wilson-Art 40 sheen with a sandblast texture. However over time and after Dynamo bought Tornado, they changed to Pionite on the first Dynamo built tables, later they changed back to Wilson-Artor maybe to Nevamar on the blonde table series. Pionite has always been the cheapest of the three and there spec is not 40 sheen but more like 75 or 80 sheen. Pionite doesn't have a sandblast texture either, it is called eggshell. The Pionite Hpl is slick dark green even though the color of the laminate has nothing to do with how slick it is.
Today I beleave the Mexican tables are using something similar to Pionite. The coin-ops are still made in Fort Worth and I beleave the surface is made currently by Wilson-Art. Wilson-Art is my preferred material.
