I used to have some and although they were very stiff for their weight, and they were reliable, I don’t think the damping in them is anywhere near as good, or easily tuneable as the latest Pikes (or the old Fox RLC dampers); for aggressive riding, I found them just too linear, but also lacking the initial suppleness of the Pikes. Basically, good forks let down by mediocre damping. Intermediate services are very straightforward on the Pikes, and there are loads of online servicing & tuning guides. (if you do decide on Pikes, it could be worth a look at the German online retailers, as when I bought mine, they were miles cheaper than CRC etc).
