I have several of those, but I'm still drooling all over my keyboard. As far as my Dunlops go, it's hard for me to really tell what the difference is between them, in terms of stiffness, etc. All produce about the same amount of spin. They all feel relatively plush (except for the F2.0... that thing is much stiffer), especially compared to today's racquets. They got progressively lighter over the iterations, if ever so slightly. The Rev, with leather, pushes up over 13oz. (13.2, maybe). I used that as my main racquet for a while, strung with Bow Brand natural gut. Man, was that sweet. By the time I got that, it had been discontinued for a while, and Dunlop was at the end of the MW era. I got it on a super discount from a golf (mostly) store for $30, brand new. That's the theme with my 200 collection... got them all cheap. That one for $30, MW was given to me, HM I had gotten cheap, then it was stolen, then my girlfriend (wife, now) bought me a replacement for my birthday. M-Fil for $40ish, M-Fil Plus for $25 off of Craigslist, 4D for $20, 4D Tour on crazy discount from TW. They had a March Madness bracket for products with a larger discount for however far they got in the "tournament". Somehow, I got two discounts and got it brand new for $35. Bio and Classic, as I said, got them for $60 total, F2.0 for $45, and a friend found the Max 200G at a thrift store for $20 and refused payment when I tried to give him money. All in all, they play relatively the same, as one would expect. I've used the Rev, MW, and HM the most. Haven't really given the rest as much attention as they deserve. The one I've played the worst with is the 4D Tour. Heavy, not nearly as headlight as the rest, open pattern. Kind of like Prestiges. I have, but have never gelled with, the Youtek Prestige Pro. Something about the open pattern. And I think you're right with regard to the F2.0. Seems close to a Six.One mold. I think it may from Dunlop's mold they used for Tommy Robredo's racquets (Option C, or B... I don't know which).
