One particular oddity is wilsons idea to wrap certain families up with completely different frame types. This may or may not apply to you but the steam originally came in a bunch of different versions.
steam 95
steam pro (95)
steam 96
steam 99
steam 99s
steam 100
steam 105
steam 105s
the 95 and steam pro, as well as newer steam 96 were all decedents of the older Hammer wilson racquets, which themselves evolved into the wilson tour racquets before turning into the steams.
And you think that it confusing?
the steams in 99, 99s, 100 and 105/105s were actually pretty close to the wilson juice line. Except the juice pro 96, which was a closer racquet to the wilson tour line, but used a different mod from the tours.
The 3 95 versions of the steam (95, pro and 96 [which i believe is a 95 tour mod as i have compared to several version of the tour]) were repackaged and are now closest to the new burn 95, which has no similarities to the new burn 100, 100s. The burn 100 team is an older wilson racquet with the newer burn paint job, hence the power poles of whatever they are called. And the standard burn line and the burn FST line share nothing in common between them besides a name.
what can you take away from this?
well a couple things, one is that you really need to research when you buy a wilson frame. The steam line was always marketed to major spin and power... but if you did your research you would find 3 versions , and 2 in particular that decended from some of the most popular Wilson tour and hammer racquets ever made, nothing like their 99s 105s brothers.
another thing is not to discount older wilson racquets. You could go out and buy the very newest version of the wilson burn 95. yes its on sale right now for 120, but i bet when the 95 CV drops it won't be. It doesnt play radically differently from any of the previous wilson tour, or even hammer racquets. same with the blade line. you can pick up very very cheap new wilson blades on the bay that play similar, if not better than the newer CV version. Not much has really changed in the way that wilson manufactures its racquets, even if they have "new versions" rolling out every year. They are really banking on consumers not taking the time to realize that are really buying the same product year after year.
