best gap to be on swsro?

i was wondering what the best gap would be?
i am a hybrid int spear char and currently on a 2 gap but ive started to struggle a bit on sp, maybe 3 gap?
whats your ideas (btw i dont want to buy sp at this stage, i plan to do that later on around lvl 80)
thanks

You don't need to buy sp. Farm for a while with gap9 then go with gap2-3.

9gap at lvl 42 = awesome.
