Thanks for the input. I live in Florida so the hills are pretty minor around here and thankfully the few we do have are not on my route. I do have a slight incline, maybe 4-5%, that goes for about 1/2 mile. The nice part is that it's a ridge so it goes back down the other side.
So, I ordered a Salsa Casseroll SS from the LBS. I'll give it a go for a while as a SS. I don't think FG is really for me. If the SS proves to be too much (or too little rather) then I can always throw on some gears since the frame is made to handle it. And who knows how it might end up? I can even see the scenario where the Casseroll becomes the general purpose bike and the LHT is the commuter but I'm going to give the SS thing a good run first.
