If you are going to get an X-Force, wait for the '09. I shot the new X-Force SS bow today (only one the shop had) and I was very impressed with the feel of the bow. I can't say it was an apples to apples comparison (because it was the SS and not the Dream Season which I want to try), but the shop owners told me the feel is pretty much the same on all of them because they all have the same cams. Anyway, my complaints on the old X-Force was the lack of valley and the letoff (in defense of the bow, I only had it for about a week and the draw length was probably too long). The new X-Forces now have a valley, better letoff, and what appears to be a more accurate draw length. The bow feels so much more comfortable to hold.

I also shot the new Bowtechs as well. They are an improvement over the previous center pivots IMO with a better back wall and letoff. I didn't feel any vibration, but to me the Guardian I had still seemed more quiet. They will definitely be solid bows this year. That being said, they didn't overwhelm me enough to make me want to switch from my current setups (see signature). However, I think the new PSE's could. The SS I shot didn't have any vibration, and noise level felt pretty close to the Bowtechs IMO. With the new feel of the PSE's and added bonus of speed, it would be hard to pass on the new X-Force. I know I'm saving up for one right now.
