Tough spot.
For anyone new to AFS I would tell them that it isn't a low end brand. If you compare it to something like KT low end the AFS will lose every single time.
Here's a comparison of the smaller surf foils that touches on that:
www.wouzel.com/post/quick-comparison-afs-silk-code-x-kt-nomadWhat you get from AFS is buttery smooth riding when at medium to high power. If you compare it back to back with the KT stuff you can sense the camber "noise" or "feedback" that isn't as smooth but gives insane low end.
For me, I've leaned on having super fast boards with my AFS stuff and good technique for takeoff in the bumps. I never found much difference in tail sizes for initial lift but can say the UG41 is a legendary tail vs the HA38 which I disliked all the way.
Jeroensurf might be able to help out with bigger size recommendations and I would love to hear how the new silk 1150 rides!
