Many people like the GF HiFi. I ride a Superlight and love the bike. It's about as close to a hardtail climbing as you can get but cushy coming down hill. Only complaint, my bike came with Shimano Avid Juicy 5 Hydraulic disc brakes. They have been nothing but problems. Waiting right now for Shimano to replace the brakes for me. Thank goodness I still have my hard to ride!
Thanks for your experience. It's such a hard decision because I love my dh's superlight, I would probably use it more but it's a large and I really need a small. I can't wait to ride a mtb that actually fits me.
