I have two pairs of TM's, both of which are mounted at true center. I really like them. I live in southwest michigan and they work pretty well on the crud and are nice in the park. I have the 05 models in a 165, and I love those at true center. I also have the 07's in a 175 at true, but I don't know how much I like them there. I've heard that they didn't change anything between the models but in my personal experience I find the flex patterns much different. I probably should have mounted my 07's at -2 or so from true in hindsight, I may eventually if I feel like it.
