6 Handed vs 10 handed in $50+4

[bcubed72]

I've been playing the $50+4 tourneys at Pacific recently. Initially, all they had was 6 handed, so that's what I played. After 15 days and about 130 tourneys, I'm ITM 60%, w/ ROI of 12%. I know this is short-term, but bear with me. I'm writing because Pacific just started offering $50+4 10 handed. I'm wondering which game to play to maximize my HOURLY rate. The levels are identical, as are the number of paid positions (3). I'm thinking the six-handed game might be better, because you get to make almost the same number of decisions, but (due to fewer players) you make them in less time than the 10-handed table.
Which tournament do you think maximizes hourly rate? Would this change if I was interested in maximizing ROI?
