Stars 55$ Turbos - 105$ Turbos - Difference?

[HoRRoR]

I am playing the 55$ Turbo SnGs on Stars, before i was playing 55$ Speed on Party and actually i feel very comfortable at this limit and i am beating it quite good, 16% ROI over about 800 SnGs (4-6 Tabling all the time...)

I did a lot of cashouts, but right now i think about moving up to the next Limit and i just wanna know about the differences, obviously it will be tougher, but will it be a big difference in skill or how will it be?

Any experiences on that?
