Adding weight to nibb points

I am converting my Easton x7's to indoor 20 yard arrows, for recurve use. I am using 4" quick spin vanes at one end and would like to add weight to the hollow Easton nibb points.
Methods and material selection please.
Pre weighed lengths of solder placed in point, point then heated to melt solder and hope it sticks. ( point seperated from shaft)
Air pistol pellets, similar method to above.
Ditto but cold formed by pressing pellets into point cavity with shaped tool.
Adhesive?

Is it worth going to all of that trouble? First off, what weight are your Nibbs, how many grains are you going to add? If you manage to get your pellets (Or whatever) into your nibbs, & find that you have put in too much (Making your arrows too weak in spine), how do you get the stuff out again? Ask your club coach what He/She recomends, or get some info' from your archery dealer. If you are after doing an experiment great, let us know how you got on.
All the best with whatever you choose :)

You don't have to buy new nibbs, they are hollow. Just put a brass weight in
it and glue it to the shaft again. Make sure the weight is well fixed, using
the same thermal adhesive. A loose piece of metal inside an arrow will do
nasty things to both ends of the shaft (don't ask how I found out, if you
really must know, I will answer that by private email). Hold the nibb
vertically, heat it, using a flame or a hot air gun, and let a couple of drops
of glue run down the center hole. Then drop the (heated) weight into the hole
and push it hard to make the glue flow up along it's sides. I made my weights
slightly thinner than the hole diameter and with a threaded hole in the rear
end, to be able to remove them again. When putting the nibb back on the arrow,
don't hold it upside down or the weight may come loose.
