I went with JB weld... just because they definitely felt like they were too loose. It was all I had at the moment and I was too impatient to even ask. Works great, haven't had any loosen up yet, with a couple hundred stumps. I keep thinking I probably should have used the hot melt just so I could recycle them a little easier later. But will more than likely go with the GT insert from BigJim's next time.
My biggest regret in install... I didn't do it broadheads in to align them properly, so now I need to properly refletch them to align my arrows properly.... or just buy/build more. It falls under the old adage, You learn more through money/parts wasted.
