Yes, I use the Halcyon integrated weight system, and I like it very much. Took me a while to figure out how to bolt it onto the backplate and such. You can't drop weights accidentally. Only drawback is you can barely get 20 lbs in it. With a steel backplate and double Al 80's, I need to get a V-weight. With a steel tank plus 2lb ankleweights, the total of 29 lbs is about right for drysuit diving.
