Fishhunter:
I drill two holes in the riser and mound the retriever with #10 bolts.
Where do you get the threaded inserts for the holes?
I've never seen them for sale.
OHDeerguts:
I hate vanes on BF arrows. I think they are pretty useless, and I don't buy the arrows with them unless I need one right now, and then I just cut them off. The vanes might clear a BF Whisker Biscuit OK, but it will hit almost any other type of fest.
