% commissions are not all that relevant if you can be a consistent winner.
If you swing trade you can get 1-2% commissions but larger losses too. It's important to understand your own tolerances. Each trader is different.

Sure, but you'd still make a lot more with lower comms.
Speaking of which, why can't we have a FX world where we can trade limit orders and do away with the spread and only pay commissions?
