I just put the QAD Pro on my Drenlin for my Muly and speed goat hunt and have no Issues at all except the other day at about 34-36 yrds I wasted two arrows with a robin hood,Its quite and shoots well at 40-50-55yrds 20-30 its dead on also,however I did switch back to 4" vains being Iam not a big fan of Blazers but do use them with the DropZone and the WB.....
My shop guy sold me the Pro for 100.00 tax incluededso couldnt pass it up.
