Hi, I am rejoining the list after a long hiatus. I have a 12.5" Royce conical on order and am planning the dob structure. Ease of assembly/breakdown are key so I am leaning towards a 6-pole vs. 8-pole truss. Any advice or hidden traps I might think about? Thanks, Rob O. _______________________________________________ ATM mailing list http://www.atmlist.net/
