dirtfreak - I'm not sure.
Jake - The only place I've run T-Bones in the last year or so was the track in Vegas; blue groove and very broken up.
I run Studs at quite a few tracks. IFMAR Pins will probably work very well at Palomar when the track is wet as well.
I have an electric race at Titus on Sunday so I won't be able to make it, but I'm gonna try to make it out there the following weekend.
