I upgraded the stock spring shock on my Rockhopper with this fork and all I can say is that although it was some serious coin, it certainly resulted in putting a huge smile on my face. Downhills are not nearly as brutal and the tracking on a corner is amazing. I cut 5 minutes off my previous best lap at my favorite local trail after putting this fork on my bike. The Terralogics is simply psychic when you pedal. After setting the sag at 100psi and dialing it in, Terralogics is set to about 5 clicks out right now which gives me just the right amount of low speed plush and incredible climbing pedal when you drop the front end from 120 to 95mm of travel. The Kashima coating and black color looks amazing on my bike (Finally a NON-White Fox on my local trail and I own it!). The 15mm axle is super rigid. I can't say enough good things about this fork. Simply fantastic for aggressive XC and All mountain. If you have the coin and the need, buy immediately.
