No they do not, far from it.
A new set of Roto flats has piles more, but it dies down.
A set of TI's, new or old, has quite a bit more.
Labellas(not the Jamerson set), have a comparable top end, maybe a little more.
I guess I should have said 'any other flats I have tried' which includes Ernie Ball, D'Aquisto, and GHS. I can't imagine flats with more highs than Chromes, might as well get rounds
