I'd wait a while and see what the rrp price is on the pushed boxxer upgrade, if you can get a race plus the pushed boxxer upgrade for less than the team, hell for even a bit more than the team I'd go for that. The Pushed boxxer upgrade will greatly improve you're boxxer to out perform the World cups. Thats what I would do depending on the price of the push boxxer upgrade.
You could even pick up a cheap boxxer second hand and paint the lowers and put new decals on them and buy the pushed boxxer upgrade and it would give you an awesome fork at a minimal price.
ask pinkbike member oliverhayes. he's our local boxxpert and what he don't know about em, you can fit on the back of a postage stamp. he runs the race, with a fettled damper and an air cartridge he got for 60 quid. he'll tell you all he knows cos he's a vast fountain of bike knowledge
