I am researching forks to upgrade my GT Aggressor 1.0 with. I'm currently stuck with a 65mm travel and I'm looking to improve the travel substantially for trail riding purposes. I'm trying to stay under $200 bucks for the piece, so I'm not interested in anything too crazy. Here are a few of my options:

RockShox XC30TK

SR Suntour XCR RL MTB

RockShox Recon Silver R

Trails I'm hitting aren't mountain trails, they're forest trails with a few jumps here and there of about 3 feet. Any input is appreciated.

Also, the XC28. The only difference between it and the XC30 appears to be the diameter of the upper tube. Is this terribly important considering the 2mm difference? The cost savings are around 50-60$.
