I've been leery to post on this thread as I find some of the posters rather ignorant .
So, I have only this to say to Cargo
1) You will go nowhere, stagnate, and eventually decline in ability if you decide to rest on your laurels.
2) You have my respect for having the desire to improve yourself. A huge percentage of archers regardless of what they are shooting at could use an attitude like yours!
3) In addition, Pinwheel's tuning advice is sound. Use it.
