Dink,
I like the glue-ons because they give me options when it comes to point weight. That lets me tune the arrows to my bow. Here is the setup I use with my 46# Kanati and 47# RER:
FOC ARROW length 28.5
shaft+feathers+nock wt - 244 (Beman ICS Bowhunter, 5" shield cut, X nock)
separate insert weight? 50 gr brass
adapter weight? 45 gr long aluminum
point weight 135 Zwickey Delta or Simmons Tiger Shark
total arrow weight 474
balance length 20.50
FOC % 21.93
GPP
draw wt 46
arrow wt 474
GPP 10.30
I draw right at or just a hair under 28". I like to have the back of the broadhead touch my finger when I am at my release point, so I cut the shafts 28.5" BOP.
You could use the short aluminum insert if you wanted to get closer to 10 GPP. These paper tune like darts and shoot to the same point as my 175 grain field points. They should get you in the ballpark.
Deltas are wicked whitetail and turkey medicine!
