Rack,I had a TR Drop-Zone on my 03 SC Patriot,never would tune exactly right,launching arm needed extra shrink tubing to be quiet,and I hated the way the set screw dug into the riser.Also,keep an eye on the adjustment screws underneath,they have nasty habit of working loose.Don' t get me wroung,it' s not a bad rest,and it' s made fairly well.I just expect a lot more out of a rest for $110.00
