I've actually thought about getting some of those, but right now I'm using Nocturnal lighted nocks in my GT's and I don't know if they make a pin nock version? I doubt it cause the battery takes up too much room.
Other than that aspect, it would be a good idea and you could always remove the pin nock insert and remove the weight tubes if you wanted to.

I have never had this problem, but i'm wondering if anyone has tried putting a thin coat of silicne on the nock. That should hold it and you should be able to pull it out when you need to. My son just bought some arrows that are already weighted, we have not had any problems yet, so i'm interested in your solutions.

I was shooting my weight tubed arrows at the 3d range today and was popping out 30-40 percent of the time.   I finally lost enough and got sick of it.  I picked up a  set of pin nocks and glued them in  tonight.  Will see if that helps.   Theoretically they are glued in the same as the point adapters so they shouldn't pop out.

I glued my weight tubes in with contact cement and haven't noticed any more problems. I only built 2 arrows though, that's all I needed for now and have gotten busy with other projects.

I dislike weight tubes; carbons do better with the front loading by screw-in weights or different steel adaptors.

little bit of hot melt

I think these pin nocks are going to work.  I hit a drooper in the target this morning and splintered the shaft on one of the arrows.  I tried to get one of the glued in pin nocks out but wasn't able to.  If I can't pry one out, or even cut the arrow off one I doubt they will pop out on the shot!
