It's the same argument as the other lesser known brands where Wilson/Mizuno/Srixon (and to some extent, Cobra) struggle to get traction in woods. I would say for someone to want to try one of those brands, you'd either have to be swayed by price (at which point, they might also just be thinking of a used big brand driver) or you have to think that one of those brands will out perform TaylorMade/Callaway/Titleist/Ping. And with current clubs, there really isn't that much room for other clubs to be better than those companies, maybe a better fit at best. Personally, if I know one of those big brands work (and at the worst, be as good as those other smaller brands), why should I waste my time with these other woods?
Again, not saying that these companies make woods that are any worse than the big names, but I definitely don't think they are better either. So for me, I'm not very interested in trying smaller brands knowing that the performance gains are either non-existent or marginal at best.
