The good news is that Warrior learned from its mistakes-- it released the Burn X. The Burn X has a much better pinched face shape, more sculpted throat, faxed the problems with the sidewall stringing holes, AND lowered the price! Bottom line: buy the Burn X over the Evo 4X.Pros:
Good combo of weight to stiffness. After stringing and using this head for awhile, I feel there are a few problems with this head. Read on.Cons:
Warrior took a step backwards with this head. The Evo 4X is not as good as the 3x in terms of face shape and design. Hinges that went wrong: 1) the thickness of the sidewalls is awkwardly thick. In order to implement the SymRail, they made the sidewalls thicker. It looks awkward and aerodynamics suffers. (Head speed slows as sidewalls thicken). 2) the bottom of the sidewalls where the stringing holes are flares to the outside. This makes stringing a narrower channel impossible. 3) Warrior could trim weight in the throat with more aggressive cutouts.
