If you are planning to use mk5 for pvp and you maxing FA, you shouldn't even think about mk3+type5 for pvm, use onehander in offhand for 11s FAs. Also mk5 + onhander for pvm and mk3 + onehander for pvm doesnt require IP in MR or fling at all. I think I'll keep fling at 1271 for 6s fling on type 5 tho.
