I ordered test kits of each to figure out what works best for my set up. Question I have is do you start with what you plan to use for a broad head, pick that up front wieght and tune to that?
I would like to hear about your trials And experiences. Thank you, Adam

Read the bareshaft tuning section at A&H archery. I think it might help. It's what I use and works well for me.

I do as you stated.
Personally with screw ins I use a 175gr BH, so I tune with 175 I'm mind, no other points at all

I like the idea of choosing the broadhead I like then tuning to that weight
