MJD, the recommended throws vary so much. If you're planning on going really fast, dual rates would help. High rates 1/8" each way and low 1/16". If you don't have dual rates, stay with the high rates for your first flight and make'em short flights.
For the Surestart's, Golden Bee's and Blackwidows, 3/16" would be a good starting point.
Yeah, I really like the SWR's too. I haven't gone all that fast with mine, but Flyswatter uses carbon fibers strip as a spar when using a TD. You'll probably want to sink a spar in there or do like FS if you don't want the dihedral when you pullout. CP likes to put spars in much shorter spans. Everybody that's built an SWR oughta go together and get COMBATPIGG a copy of turbocad.
It'll be cheaper than the copyright lawsuits he's planning.[sm=lol.gif]
