Heres my setup. Viper Deluxe 55# my draw 28 1/2" CE Heritage 150's 5gpi weight tube inside, custom FF D-97 string from Chad (for now 150gr tip 100gr brass insert) but changeing to 160gr Magnus I 2blade w/100gr steel adapter, factory aluminum insert. I'm shooting pretty good back to 25yrd hold a 3 shot group w/heads inside a paper plate. Shooting great @15yrds only 1 arrow groups w/heads don't want to damage arrows. So I hope I can close the deal this fall.

I have the same bow. It shoots well for me.
