kombat 105 or 114

[Pareia]

Hi, I´m a intermediate wave sailor with a huge size 100 + Kgs.
here we have winds around 15Knots, a pretty nice waves. Today i have a mistral score 104 and use most of the time with a freestyle sail 7.0m2. wich would fit best the kombat 105 or 115? i´m afriad the 115 would too much of a freeride board...
