Erik & Roger,
"I find the 111 a little to sticky and needs a lot off power to run free!!!"
I have the '08 iS 111 and sticky has never come to mind. I weight 80 kg and have set the base in the center of the circle. I haven't experimented with the base forward or back yet, because I haven't had any problems with the center position. I have sailed it with my 7.6, 6.6, & 5.7 so far and it is a wild ride powered up. It reminds me of a mini Formual board the way it flys over chop. It certainly isn't a smooth ride, but it definitely is not "sticky" for me.
