Replying to Frustrated with scratch fs mounting

i have been getting mixed opinions on where exactly to mount them

i kinda want "modern" because even that is 6.3 cm. back
though i'll probably mount "standard" (8.3 back) because i do tons of all-mountain

a friend who rides fujatives mounted for all-mountain told me they're fine for fakie and park skiing, though i think the fujative all-mountain point is farther forward

has anyone ridden either, or better, both?

btw, i'm 5'10" about 170
i race, and my rossi 9x are the same length as my '06 scratch's, so the skis are eerily similar

but i also used to skiboard, so i can handle center-mounting

help please!
