ski looks to be coming along great. ive got a rn thats already had the rocker, tubbies, shortened rear done to it. making some repairs and upgrades. also looking at going with the rrp ninja holds. at least you didnt have 8 different paint colors to sand down before the gelcoat like i did haha. you definitely shouldnt have any problem flipping off a boat wake. the previous owner of my rn could backflip off a boat wake with a simple 61x setup with a head, bpipe, and enhancer. moving the pole forward will help you more if youre trying to flatwater flip than off a boat wake. also if you position the holds towards the rear, itll make flipping easier cause your weight is farther back.
