My bow is a 52# 25" Hoyt Ultra sport cam.5 and I use Gold Tip XT 5575's. Are these good arrow to use with this setup? Also what gr. and model broadhead should I use?

Also, what kind of sped should I be getting with this set up?

You should probably be using 3555's

I agree with Mathewsboy...you should use the 3555's. However, when it comes to broadhead choice I would recommend a fixed blade, cut on contact style due to the poundage you are shooting. I would use a 90 or 100gr. head as well. 100gr will allow for a wider selection, it is the most popular grain available. Some good choices are the Montec G5, Gametracker First Cut 90 and similar ones...there are many out there but make sure they are tuned to your arrows.

I think with your setup you would be best off with the 3555's and a sharp broadhead like a steelforce cut on impact.

I tried to figure my KE for my setup but I didn't know what SE/PDW meant. Does anyone know?
