The M2 fiberglass crossboom is actually two sections of fiberglass tubing with an aluminum billet slug where the elevation rotator attaches. I think solid fiberglass rod might be a bit heavy and too flexible.
I use a sold 12 foot fiberglass rod for elevation. it is a 1.25". but it was a bit narrow and will somtimes slip at the M2 antenna brackts. The 550 rotor held it fine. I plan on replacing it with a 1.5 inche solid this fall. http://www.strongwell.com/products/pultruded_prod/struc_shapes/
the 1.5 inch is part # 110051-01
it comes in 20 foot sizes.

I had the same issue, I used a 1.25" fiberglass boom with the M2 antennas. I recently replaced the stock M2 u-bolts (which are designed for 2" masting) with smaller u-bolts that now keep the antennas solidly in place. DX engineering has a nice supply of bolts and saddles, the quality is very good.
