I have a suggestion for you...
Quest BMX Miyagi Bars (Check them out Link in my Sig) The Bars are awesome, They are..
8.75" Height
27" Width
3 Up
6 Back
7/8" Cross Bar (Same as the rest of the Bar)
Straight Gauge .065" Tubing all round
No ultra mega butting or stupidly small O.D Cross Bars here! they have a lower 5" Cross Bar which will make it easier to step over them. The are 2-Piece Bars that have been designed for Strength & with Flatland Riding in mind!
AND.. I will be coupling them with a 36mm Long Madera Mast Top Load Stem which has a 35mm (About 1.5") Rise which will put the Quest Bars at 10.25" in height & then if you have spacers under your Stem or a Large Stack Height Headset Cap also you could get 11"+ Feeling Bars!
That would be my suggestion for you
