I've been 1x10 for a couple years. Up front is a 38 with an 11x36 in the back. When I want an easier gear I think about singlespeeders and quit whining. For me having more top end speed is more important than an easier granny gear.
I've used the paul and mrp chainguides but my favorite is the e*13 xcx-st e-type. I also used to get a lot of chain-slap or the chain would come off if I back pedaled, but since switching to a medium cage rear deraillure there's better chain tension and it's gotten a lot better.
