I dropped down to 150 class stuff after I first started playing. The lighter weight was easier on my shoulder (2 rotators cuff surgeries) I was throwing further and was OK with that. My form got better and distance came along with that, then hit a dead end. I stepped up to some 165-170 stuff in the molds I was thowing at the time and started throwing further and with better consistency. The weight was not a problem on my shoulder because my form was better. I'm also a athletic build and was trying to power through , not throwing correctly. I think getting some 170 stuff and doing some field work would benefit you. I found the heavier disc are also easier to replace, the lighter molds really vary in flight from disc to disc, with the heavier disc having the same flight from disc to disc. Bottom line I think my consistency got better by throwing heavier disc, and I had more molds to choose from.
