PowerBlock Grip/Handle Types?

[atxguy24]

Does anyone know how many different grip types there are floating around out there for the various PowerBlock sets? I know of at least three:

-Pro Rexan grips: These are neoprene, and they are not contoured at all . . . just a straight grip

-Elite grips: These are also straight, but they are rubber I believe. I've never done a side by side, but they seem like they might be a bit wider than the Rexan grips.

-Sport/Urethane grips: These are fat, ergonomically contoured grips made of rubber(?)

I have a 5-85 Pro Rexan set, and I love the grips even if they might be a tad bit slender. I just picked up some U-90 stage 1's (5-50), and I am not a fan of the grip at all. I'm not super particular about the different PowerBlock sets and block material, but the grips do make a pretty big functional difference IMO and is a sticking point for me in terms of a purchasing decision.

Does anyone know if there have been any other grip/handle types across the various PB models?
