Not done loads of running with mine, but thus far I love my BMAX!
having run an B44 a couple of years ago, the BMAX is easier to drive i think, very forgiving, and is very predictable. Works well out of the box too. Plently of guys here to bounce idea's/set ups off too. I've not broken any shock towers on mine yet, but def invest in the carbon ones. looking at them they'll break whatever you hit before they break!!
BMAX - FTW
