Wets - No
Fun -Yes
You are all big girls who need to learn how to ride!
On a serious note, I have mentioned before that wets will increase the speed if you do have an accident. Tough call. Wets or not, you can only go as fast as you feel safe, and I am glad the road tyres slow us down... I'd hate to have to go quickly in the wet.
We would have used them for Sunday at Cadwell last year, and we would have used them for half a race at Snett.... I am not sure any less people would have crashed. It is a lot of extra bulk for me to try to find in an overloaded car.
About the lack of tread at the tyre edge... I heard in a press release for another tyre that in the wet you do not lean as far, so they stop the tread at the limit of where any sane person would lean in the wet... This allows a slicker/frillier edge for the dry.
