I would use bryntoll in MH and only in MH. Bryntoll sucks in OH. NOw equipping bryntoll will leave a big hole in your expertise cap so you might wanna pick up http://www.wowhead.com/item=50467 from frost emblems and http://www.wowhead.com/item=50180 from BQL 25 man. Other way to do the same is to pick up the cloak and warrior t10 pants.
Regem whatever slot you will need to regem for arp hard cap.
