Well personally i dont have experience in spot forex but i have friends who have and are very keen on prop positions because of lack of capital. Also don't forget you can have more of a crack at a prop firm knowing if you lose a fortune you aren't left holding the bag. Lets be honest thats why most profitable traders remain at prop firms.
The profit split doesnt bother me at all if your split is 50/50 then just use 2x the size you would use on your personal account.
