Congrats on a great buck! I also shoot a Hoyt TEC series and use the Steelhead 100s..... AWESOME combo! The Rocket Steelhead threads are on the short side for GoldTip inserts, for some reason other brands and companies don't seem to be a problem. However, because of the popularity of GT shafts Rocket will be extending the thread count on their Steelhead 100. They did manage to add a couple of more threads with their 100XP design already. Congrats again on a fine animal.
