memory wire issues

[magentablue.livejournal.com]

I have a couple of questions for you jewelry makers out there... I recently started working with memory wire and i am having a few problems. First, I like the look of using end caps vs. bending the wire at the ends but I don't know what sort of glue works well. I tried super glue and it doesn't seem to be working too well. I figured I would ask here for some suggestions before i go out and buy every glue in the world and start experimenting. Also, I am having trouble getting my crimp beads to stay in place on the memory wire. Is there a particular size that works better? I also suspect it is possible that my crimping pliers are just worn out - they were a cheap pair from Michael's - but I was wondering if anyone else was having problems?

Thanks!
