I've heard mixed things about the Phase 1.3. Mostly that the frame is very good, but the rest will not last you long as you improve. How long have you been riding trials? Are you just starting? If so, the 1.3 would be ok, but you will pretty soon find that the brakes are not up to much. The problem is that the Phase 1.3 comes with a disc only fork, so if you wanted to put Maguras on it, you couldn't. And the back V-brake will be pretty poo. But can be upgraded to Maguras witht he Evo II mounts. I was looking at getting a Phase 1.3 for a second bike to play around on. I've come to the conclusion that the Phase 1.2 whilst being more expensive, will last SO much longer. Well, that's what's right for me. In essence, if you can afford a phase 1.2 with the HS33s, then do (£430 here ). In my opinion! Try riding them both and see which feels better. Hope that helps Dug
