I am riding the 133 08 Thorn, and it was exactly what the doctor ordered. I think the wider board gives me the better low end, I find the board better in chop than last years. It does ride different from last years, but softer which is good for me. It took some time to get used to especially since I also went up in length from 131. The 133 gives me lots pop, but also super good control. I really like the footstraps, with more toe grip than last year, but still super comfy
The 07 might have had a slightly better pop, or I though so in the beginning, but once I got used to it, I have plenty. I think the biggest difference was doing powered bottom turns, the wider board did throw me off a little..for a while.
The board feels heavy on the ground, but I don't feel it at all while riding. I don;t think the UG feels very much lighter though, which makes sense since they are both wood board (the new ones). Also the me and chinstrap must ride radically different because I don't at all get the spray s/he is talking about. I did get it from the UG flx boards, and was one of the main reasons for me to seek something else. THat said his UG board is one of the boards that are really good. The 05 UG had a single concave and the board seemed to work great. Now they come out with a double concave and thus ride a little differently. Still good though. Whereas the thorn has a nudge in the corner of the board that deflects water that otherwise would spray you, I think the flx felt like it had a spray that kept on hitting me on the nose...even if I tried to move my body. Funny how different we all are, but the spray factor on the flx is one of the things that ended up being very annoying for me...
