ribs vs Staggered ribs vs minipins

[Bluestreak]

Ok guys so I've been advised by a few people about front tyres for my 2wd cobra (that currently has too much front grip), to use either Ribs, staggered ribs, or mini pins. Car will be raced indoors on carpet.

So I thought I'd throw it open to everyone to ask what are the relative merits of these types of tyres as I'm getting a few conflicting suggestions at the mo. This is obviously ment with no disrespect to the guys who have already offered advice as all is gratefully recieved. I just thought I'd get as many opinions as I could at the mo.

Car currently has dBoots Terrabytes on the front which are just too aggressive.

thanks in advance for all input
