Pins/spikes fluff the carpet and ruin grip for onroad classes.
I've ran tourers and GT12 on tracks shared with buggies and after every race I am spending a few minutes clearing the carpet fibres from the axles and driveshafts to prevent binding.
I raced my Mardave on an LMP/GT12 only carpet track a couple of weeks ago and what a difference! No carpet fibres at all, just a few specks of foam/additive deposits on the chassis. Grip levels were absolutely epic and extremely consistent over the whole track.
Venoms work well on buggies with additive if temperatures are 12c+, slightly less lateral grip than pins but equal in a straight line.
I've been running Contact RC foams on my Losi 22, wear rate is very good. Grip levels are less than pins but more consistent through the night. Mind you, I wouldn't want to run the buggy at the LMP/GT12 track, it would traction roll at every corner!
