I'm a newbie to mtn biking, only been at it a year. My bike is a Giant Warp DS2 and it came with the RS Pilot XC. I have never had issues with it, I really like it. I had to add a bit of air initially to set it up for my weight (~190 lbs) and once again after the bike sat all winter. I primarily just ride XC with no big drops or anything like that. The bike probably has around 500 miles on it now. I have noticed that the Warps come with the Judy now instead of the Pilot, I don't know the differences really. On the Rockshox websight it says that the pilot is an upgrade from the Judy. Good luck.
