Hi Andrea! I've been your fan since I just read "Insert Smartass comment here"!And your "Brickhouse" concept has gotten my brickhouse girlfriend to finally come race with me! As you can imagine, she's not a toothpick and she's strong and fast! Great advice on considering my fit for TT position. I've heard it's not the most comfy - although I do have huge back flexibility- and usually I don't ride TT's longer than 20K, so it should be fine. And I'm thinking that my hands won't go numb in the aero bars! The link to fast twitch was great information, I'll read it a few more times before I go in on Friday. Thanks so much for your information! Carol
