Hi Leysenkr,
The isonic are more direct, small mistake on Futura didn t have really an effect your speed but isonic yes. But don t be afraid the board is not hard just if you ride a race machine is better to use minimum 3 cams sails like Overdirve so your 8.5 will be perfect.
By the way you will plane earlier with the iSonic 121 than the Futura 133 despite the volume difference, this difference come from the wider tail
If you ride already Futura 101 with 6.2, you should have enough experience to use a big iSonic like the 121
Hope this help
All the best
