mraynor1, I checked Jackson's site.
Evolution 500: 27", 408 gr, 12.5% FOC
Redline 520: 27", 352 gr, 11.3% FOC
PSE Extreme 100: 27", 315 gr, 11.1% FOC
PSE Extreme 200: 27", 330 gr, 10.7 FOC
All figured with 100 gr tip. I'd say you'll still be OK with a 125 gr. That would add weight and FOC (front ofcenter [balance]).
Of these, I'd pick the Redline. The PSE 100 is pretty light for hunting, IMO. The 200 may be too stiff, but still shoot OK.
I don't know the speed of your bow, but you would benefit from a lighter arrow, IMO. Your problem when moving back may be one or two things. Form or bow tune, or both. It's not unusual to need to use the lower pin when moving back 5 yds, especially with low draw weight and heavy arrows. If you shoot fine with field points, but not broadheads, it may be a tuning or arrow issue.
