I went through this same decision for my 05 Vector... I already upgraded the skid with Ohlins and wanted to next go with Fox Floats up front. However, after talking to a few shock experts (Bruce @ Pioneer and Ross @ Hygear) and getting some seat time on my buddy's RTX, I decided that a premium coilover shock is still superior to the Fox Floats. Yes, the Floats will save you some weight and offer a rising rate "spring" for the big bumps, but you can tune a coilover to do the same (except the weight savings, but we're only talking a few pounds that really becomes insignificant when you consider the effects of ice buildup, rider weights, full vs. empty gas tank, etc.) Did you get a chance to read the recent magazine article about Hygear's Float upgrade kit. Hygear has to do ~ $800 worth of additional upgrades to the Floats to get them to offer good all around trial performance in addition to the natural big bump capability. Ross at Hygear opinion is that you can't beat the perfromance of a coilover when tuned properly. Bruce at Pioneer seems to support that opinion as well. In fact, Bruce likes the GYTR shocks that Yammy puts on the GT sleds. You get adjustability for both rebound and compression dampening while the Ohlin only gives you compression adjustment. I was lucky and picked up a brand new set of GYTR's off a guy's 07 Apex GT because he wanted to upgrade to Ohlins right out of the gate. These shocks are very well build, almost rivaling the quality of an Ohlin. The only downfall is that you can't get all the parts if you break something. Only a select group of parts are available for servicing the shock like seals, pistons, shims, etc. So, if you wad-up your front end on tree and bend a shock shaft, you're buying whole new assy, but they only list for $305 ea which is quite reasonable.
So, my vote for you is to pickup a set of GYTR's for their features, availability, adjustablility and relatively low cost. Fox's are definitely a nice shock, but they have been build specifically for banging big bumps all day and seem to be just bragging rights for people who don't really need them.
My 2-cents...
