I recently switched to Muzzy 4 blades (from Spitfire 100gr.) and I found that my vertical was off by about 1 1/2" (low) at 20yrds and 3" (low)at 30yrds. I adjusted my sight and now practice using the Muzzy field tips and they fly exactly like their broadheads. I would just suggest adjusting your pins so they reflect actual yardage - you wouldn't want there to be another element of possible confusion when taking the shot that counts.
