So on Carpet without a groove like at a big race do you think Jaco dbl pinks would be a good choice?
Ike- Really tough for me to say since we don't race on that type of surface. Maybe someone else can offer some advice.
My guess would be that if you are on CRC Fastrak II carpet and no groove (i.e. lower traction) you might have better performance with softer rubber like magenta or even pink.
