Has any one used the 3Rivers Carbon Arrow Weight Tubes? they look like a good way to add weight to the shaft with out weakening the spine. They come in three sizes 3GPI,5GPI,and 8GPI im going to try out the 3GPI in the laser 2's i just built - before i got my xbow and realized im on the light side with a 386GRN built arrow counting the 100grn head, the 18 1/2 inches i can fit in the 20" shaft will bring me up to 441GRNs.

I went ahead and ordered these the only drawback i see is i now have to glue my nocks in or chance loosing them due to the jackhammer effect i hear people talking about, but i think that happens if you cut them too short and have play inside the shaft.

They have to be cut to length perfectly or they will nock out components
