Ok... I admit I've been away from the game for a few years and just recently started playing again, but what is all the hype over these Revo shafts? When I go to the usual groups and sites, it's all I seem to hear about. $500 synthetic shafts that no retailers can keep in stock. I haven't seen this kind of phenomenon since the Nintendo Wii came out. What's the deal? Is it no longer possible to win a game without them?
