iSonic 2011 board set for a light weight

[shinobi]

Hey all, after various discussions about the iSonic 2011 for more average weight people, I wonder about the iSonic’s for a person of my weight ~63Kg.
Currently I’m using the 2010 iSonic 121 and 101 plus a 2009 86 in the Japanese race circuit and I'm very happy with the general performance.

As the new boards are supposed to arrive within this month, I thought about asking for your recommendation.
For example, do I need the 117 wide or is the 117 enough? ==> The 121 with a 44R16 gets pretty powered with a 8.5 race sails. Hence I’m not sure for what board I should go.

Please advise.
