Looser trucks will train your legs and mind better. Anyone can ride a stiff plank down a hill. Its the better skaters who can hop on any board, tight or loose, and still be comfortable. I like to think my loose preference saved my ass on a 40mph run awhile back. Ran trucks wayyy too loose for the hill I was on, and probably had the worst possible speed wobbles anyone can ever have without dying. Kept my mind focused the whole time and thought positive all the way down and made it, if it were any of my friends who like to run VERY tight setups with their evo's n **** they would have fallen in a heartbeat. Its tough, but you'll be better off in the long run.
