i reckon as you are a reasonably big fella you ought to consider ditching some stem spacers and running a wider bar; it would balance your position on the bike better, letting you put some weight on the front wheel when you need to. slack angled, long forked, high handlebar-ed bikes are all well and good down fast, straight stuff but try carving a turn over loose or bumpy ground and you will will see why Dhers try and get the front end as low as they can (within reason).
nice bike, i run my brakes like yours too. those e13's are twice the weight of most other bash rings though. flatboys are brillant pedals but you can get some almost as good at half the weight. you could save a pound just changing those two parts! its your build though…
(say you have your e13 for bashing through rock gardens, it sounds more 'core)
