I have a 21v and this year have changed the ballast around. We have 1100 lb sac in v-drive locker (surf side) and then 2-400lb V-drive sacs on surf side rear seat. Wake plate was 50% down with speed of 10.5-11mph.
IMO, you need more weight and try adjusting the wake plate to clean the wave up.
I have tried bow weight and ski locker wt and it doesn't work for me. Start at the surf side rear corner (like you did), make changes and see what works.
