First ride w/ the DIY pannier and as predicted, my back was less sweaty. Some extra understeer due to the added weight, but otherwise a fine ride. Skipping takes a bit more effort, but that's to be expected. Saw a bunch of commuters on E61st that probably got off the Q'boro bridge at the same time this morning and cut through traffic w/ two kids on bmx' and another commuter on a mtb.
