The Shimano 6 speed 14-34T freewheel is about $10 and it is another $20 for an SRAM PC 870 chain, so for $30 I can get a gear that I think will work for me. I will try the triple if it doesn't work out, or maybe a compact double. I don't think I would have any trouble with a 50/34 on the front and a 14-34 on the back.
