San manuel 2/4 ho'em

[SpaceFoo]

I play moslty at san manuel low limites. And am a small winner at them. Though 4/8 seems to be better with the small blind 2 and the big 4. the 2/4 and 3/6 does not. at theses levels 4 dollars are dropped, at 2/4 2 for small 2 for big, at 3/6 1 for the small and 3 for the big, both with a 1 dollar jackpot drop.
What i was wondering with the rake are these limits worth playing?

I am a consistent small winnner but should i play 2 times a week at 4/8. or keep playing 3-4 times a week at 2/4 or 3/6?
