plus 60 is , in my opinion too extreme bb height for a stock.....you get more backwheel control, as your weights farther back on the bike ( therefore closer to the rear axle, similar to having shorter chainstays ), but, the front ends harder to lift, your centre of gravity is far higher, bunnyhops are extremely hard...manuals are nigh on impossible backwheel control would be quite as lot harder, although if you have a modern stock with 375-380cs and a light front end this might not be too much of a problem.... ive had a +10 coust, a +10 pitbull and a +25 zenith.....the backwheel control is so much easier on the znith , but the 5mm shorter chainstays on the pitbull compared to the coust changed the backwheel handling a lot. With plus 10 you're obviously, say, 5cm lower down from the ledge so rthats an obvious disadvantage... i think taps, bunnyhops manuals etc are better on low bb........and sidehops and static backwheeling is easier on a higher bb +10 definitely does feel heavier to handle, although this can also be attributed to longer cs and longer wheelbase and actual weight and so can be combated. Edit: oh great tarty adam's reading....i think im going to get majorly corrected
