What's your opinion on beads?

A 12mm cone bead or oval ("football") bead might be just what you need.

I use 10mm bead darts in my .40 all the time; cheap and fast.

BGers either love them or hate them; there doesn't seem to be a middle bead ground.

Pros: Water proof, fray proof, and you can use PVC cement instead of glue.

Cons: Got to roll cones.

Still, if you HAVE to roll, it's the way to go. Your last ready-to-shoot option might be ear specula.
