I've made a lot of bridge hammocks, and with almost all of them I use Easton aluminum poles I get from questoutfitters.com
oh yeah, you said "lightweight." Hmm.
BER has done some experimenting with carbon fiber poles that are something like half the weight of the aluminum ones. I bought some of that to try out one of these days, but haven't yet. In the most straightforward approach you have a one-piece spreader bar, whereas with the Easton's they break down into two pieces, easier to pack. Someone (BER?, egrant5392?) tried making a two-piece set-up with his carbon poles, but haven't heard just how that worked out.
Finally, I think you can purchase replacement poles from JRB for the BMBH. These are lighter than the Easton's, but also narrower---30" vs. 36".
