OK Throttlemeister costs twice what the TopGun weights and a Vista Cruise cost. The TM weighs about 1/2-1oz more than TopGun and has some cooler finishes. Question is 1.) which works better as a throttle lock and 2.) will the slightly extra weight of the TM be an improvement over TopGun? I don't mind spending the extra money if there are tangible benefits one over the other.
