$109 maybe moving to $215 SNG's on pp (1 table)

[RikaKazak]

Hi guys,
I play the 55's and the 109's buy in on pp, the SNG's, and have a win rate of about 48.5% according to poker prophecy. I have the bank roll to play the $215's, I was curious if A.) they're that much harder than the 109's and B.) if there are sophisticated teams working it, cause I notice teams here and again on 55's and 109's but they are usually so weak of players anyways, that it's still positive ev to play vs. them, what do you think about me maybe moving to the 215's? yes or no? and if so why? and if I do move, any special considerations or anything from players that have done it?

thanks in advance
