I have my back up bow set up with a string tracker for hunting rainy days.
Muzzy 125, 4"low sounds about right. Luckily for me I am dead at twenty using my 30 yard pin when using the string tracker. So I just keep the shots to within 20 yards and use my 30 yard pin.- This is my plan of attack since I've never shot one while using this set up. But, I will not hunt in the rain without it after loosing a deer to the rain some five years ago.
