Howdy fellow Okie... I'm in Tulsa OK.
When shooting the mechanicals, the key thing to consider is kenetic energy as you need to ensure the mechanical tip opens up on impact. There are some KE calculators online such as
http://www.archeryhq.com/kin.htm (be sure you're using Microsofts Internet Explorer for this one to work) that will give you your KE numbers. I believe the general consensus is that you should be generating 65 lbs of Kinetic Energy when considering mechanicals.
All that aside, paper tuning your bow is key. You want your arrow to fly straight and not kick out to one side or another. Also consider your arrows when tuning and insure you're not underspined.
Anyway, I shoot a PSE as well and love it. It'll drive tacs I tell ya!
