I shoot the 22 Pro's and find they are very consistent. As with any large diameter shaft it has thin walls so can be broken easier than smaller shafts. This leads me to shoot multiple spots when practicing, and don't miss when shooting anything else. Of course, anybody who pays for this quality of arrow shouldn't be missing very often anyway.
I have shot the 5575 gold tips since I bought my first bow. That's all I use, if it isn't broke, don't fix it. I've never had one break, or bend. I have had an insert or two bend out of the end. Great arrows!!!
GT 22 Pro Ultralights are the way to go. Strong, and durable. The pin nocks are the only way to go and put the glue in tips. I would recomend what weight if I knew your setup. Cut them 1/2" in front of the rest and shoot em'. If that dosen't work then let me know.
