I wanna know too, I have same setup with old I76

I used a 6.6 a little with my wizard 114.
For the foilx 145 which has similar width to the wizard 130, a 7.0 worked well and an 8.0 didn't give me much more. It felt cramped onboard to me.
The 8.0 works well on my 95cm wide board but I don't bother with the smaller boards on the sail that big. I only really use it when I'm lazy and don't want to fuss with the 9.0hgo.
Can use the 7.0 on a freestyle 115 too but I am not going to bother going bigger.

6.0 7.0 and 8.0 foilglides laid over each other.


7.0 over the 8.0.


The 7.5 gator over the 7.0 foil glide. To Paducah's point the 7.0 does seem kind of big?

I used my 125 Wizard with i76 foil up to old Tush twin cam 7.4 very happily. Narrow happy wind range though before getting too lifty. When the sail is that big (and smaller too) you need a fixed centre of effort. You do not want forces moving back and forward, so although a lot of original advice for learners on this forum is rig the sail with some pump in it ie less down haul, I would disagree. Fully down hauled so it's locked in so you're not fighting the drive and lift all the time.

I used a Sailworks Flyer 8.0 when I had my first-generation Wizard 125L, it was perfectly fine, I don't recall any issues. At the time the Slingy website had something like a 6.2 as the recommended max for that board, lol. What a great board that was.
