how good is your average winning 109er???

i recently moved up to the 109s and righ now im gettin my balls handed to me....im running real bad too....whats the difference between a good 55er (17+roi) and a winning 109er(10+roi) in terms of skills......is the skill level that far apart....im getting to bubble play too often to have a less than 30% itm.....any advice adapting to the tighter players and to the higher number of players at higher levels
