So, I bought a dozen 33/55 GTs from a member here. I thought the arrows I have been shooting were the same length, 29". Turns out the arrows I have on hand are 28". So, the new ones are 1 inch longer. I am hoping for a serendipitous outcome from my error. Adding an inch would make the spine slightly weaker correct? I have only tried the one arrow (28") with my new bow so...this might turn out fine.
Also, I bought a bowfishing kit from Sportsman's Warehouse last night. They have a pretty good selection of equipment. I was pleasantly surprised. But, no stabilizer adapters. I didn't figure they would have those anyway. I guess I will order one from 3Rivers unless someone has better advice.
