I want to buy a early planing Isonic above my Isonic 122 ( 2008, 114 liters ).
I'm 87 kg.
I'm now surfing with:
* Isonic 105 ( 2006 ) with Tushingham X-15 sails ( 6,4m and 7,6 m )
* Isonic 122 with Tushingham X-15 7,6 m and with a Tushingham Lightning 8,5m
* Falcon slalom 145 ( 2007 ) with the Tushingham lightnings 8,5m and 9,4m.
I want to change the Falcon for a;
* Isonic 131 or a isonic 144.
Or must I go for the mini-formula Isonic 150?
In the past I have had a starboard Formula 159.
Nowadays I don't like the big formula boards anymore ( to heavy and to exhausting
Can you advise me.
