Ive just got a isonic 107 but finding a 38" deep tuttle is near imposable please help.

Jas,

The current iSonic 107 does use a deep Tuttle box, but as Waiting says, you can use a standard Tuttle fin in its place. Note that you'll have to use LONG bolts to secure the fin in the box.

Here is a link to fins that might interest you: select the fin you want, in the size you want, then click on the fin and it will show you whether the fin is available in standard or deep Tuttle configuration (the V Max Slam looks interesting).
