Width i aim for 28/29, but with a big rise, i currently use the Primo Samsquash bars (spelling?) which come in at 28 x 8.7 higher bars are so much nicer than smaller ones. I see a lot of riders run Mutiny glams, but after owning a set for 5 moths, and then bending then, im not too keen; though i have heard good things about the glamroids, but there lower than mine so meh.
Good tip, run around 40-50 psi for street. Dry, clean, well maintained concrete park, 100 psi. makes the bikes come up nicer. Also the stem has loads to do with how a bike feels, for the love of god, don't get a down low stem. Sososo pointless.
