Reaction time difference, bias ply vs. radial slick

The Gremlin is lobbying me to invest in a set along with a set of rims since I didn't know about the 26 inch radial till today! Gremlin also runs 20-2 lbs, but I could see running 30lbs in the radial with ease. Tire weight increase is around 5lbs a piece for the radial versus bias.

Don't know how it would affect RT in a beast like the Gremlin, might slow it down dead hooking into a crowd pleasing wheelie of say a couple of inches, vesus the pro-stock style launch it sports with the bias.

Whats the best equipment out there for measuring vehicle reaction time currently?
