Having thought about it a bit, and with the aid of some BEER to lubricate the thought processes, I'm probably going to be putting a pair of the OG Carbon bars on Pugsley in the very near future. Compared to my other bikes, the fatty doesn't get ridden as much and it'll be a good(ish) way of determining whether or not they suit me before I pull the trigger on a set for the El Mariachi.
If anyone is interested in a set of Easton EA70 flat bars, now's the time to say so ...
