Thanks all for the advice. This project has been a learning experience in what is needed to take the next step up from a loaded vertical or tossing a dipole in the trees. For the record here are the specs:
33ft (10m) Spiderbeam portable aluminum mast specifications: Extracted length 33 feet. Collapsed transport length: 53" (4 ft 5 in). Weight, 20 lbs. Bottom diameter 70mm (2.75"). Top diameter 30mm (1 1/6"). Wall thickness 2mm (1/12"). 9 segments. Anodized aluminum mast with stainless steel custom interlock clamps.http://www.vibroplex.com/contents/en-us/d25_Link___Spiderbeam_masts_for_Folding_Antennas.html
I'm also thinking I might not be using it fully extended all the time, except maybe if I'm going to be set up for an extended period like at a campsite over a weekend. Top guying will also give me a place to hang an 80M dipole too. The mast seems like it's a lot more stable than the military sectional masts, maybe because the sections get smaller as they get higher, so there's less weight in the sky? There's also a "warning mark" on the tubes that keeps a lot more of the mast inside the larger/lower section than the military types. I've messed around with the AB-86 style masts and they are much less rigid than this one.
