In For Review

I currently have some reviews in the works.  I have been using a Kurt Kinetic Trainer for a few months.  It's a bad@ss, green machine that rides just like the road.  I have a set of Specialized Fast Tracks tires, currently installed on Gus the Goblin, who will also receive his final review.  I also scored three different types of ear candy from Polk audio.  I have the 1000, 2000, and 3000 series.  As I work on these reviews, I want to cover " all the bases", so to speak.  If you are currently in the market for a trainer, tires, headphones, or a mountain bike, what questions would you have before buying ?  You can leave a comment or contact me by email.  Thanks for your help.
