Keith, many thanks for the detailed reply, hmmm you must be somewhere near Montana, as some of my family lives there and it's been in the single digits, they too are going a bit batty. As mentioned I have the barcons on there now and will certainly be riding it like that for some time, but the command shifters just seemed like a pretty good deal (down to $70 and almost new). I am not in a rush, but was just curious about a review of their functionality and durability. I was just toying with the idea and looking for options. I've used barcons on many a road bike BITD and found them good on the road, but I was thinking they would be more dicey on rough terrain, but I'll give them some ride time and then maybe see about the Kelly's.
I will, like I think just about everyone here, jump at the opportunity to buy the WTBs if they came up at a "bargain" price (aka not $475 like the pair a couple months ago on ebay). Many thanks again for your opinions and advice, as always it comes from experience and knowledge. I'll be finishing my Jelly Bean up this Friday after work and will post a pic or two on the Salsa thread....cheers and Keith I hope a "warm" front comes through!
