Difficult question. Soya'Bean has been around so much longer that I've had the pleasure of seeing him play more. But Olli has a completely unique style that has made me think about my game. At Toulouse, I looked at the way he was shooting from a back can and thought "hey, why don't I relax like that and take in so much of what's going on around me?" (Sounds lame, but I don't know how to put it into words.) He has a unique style that looks like he is reading the game soooo well.
As for Soya, well what can I say? Some of the moves I have seen him make have totally blown me away. And I've never seen him play in the states! I agree with Robbo that we haven't had the chance to witness his magic this side of the pond for some time, but cast your minds back to Campaign 2001 - that dude rocked big sticks. On his way out - I don't think so! And even if he is, he is a serious candidate for the greatest player of all paintball time.
Either one - I'd be happy and I think it could go either way. EXCEPT that I'd be on one of their teams so that would tip the scales and we'd take the win. Would be a pleasure. Nice trip - I like it!
