Anthony,
You are racing with TCRA next weekend ????
Kim is going to give them a try. I'll be wrenching for her on Sunday.
If you want to try my ISAAC, I'll bring it with me on Sunday. My helmet size is 7 1/8. The shield is a little scratched as I co-drove in a Rally car a couple of weeks back (what a blast!), anyway I underestimated the amount of tearoffs required
I'll bring it and you can try it out if you wish, if not you can just look at, feel, touch it and see what you think.
