hey mr txthroop, have you looked at a Bridge Club?
cheaper, regular dropouts, although Im not familiar or dont recall the tire clearances.
The stock model comes with a double though if i recall. I set my Troll up with a mtb triple crank, 9 speed era 44/32/22, but the double of the Bridge Club along with probably a rather large cassette gives a pretty good range.

anyway, another option to look at.
Seems to me its about 500 bucks cheaper than a stock troll, but you can look into it to find out the differences.
