Speed Hull Takeoff advice

Any advice for surfing this type of board - 7'6 CJ Nelson outlier. it's listed as a speed hull + single fin.
Long story, my cousin bought it a few months back, but hurt his back bad - told me to ride it / test it out as long as I like. He'll sell it to me for a deal if I love it.
Took it out yesterday and it was surprisingly squirrely for how big it is (7'6"). Felt almost like a shortboard on takeoff.
Has a rolled vee in the nose - flat middle - slight concave in the tail. I think the rolled v on the nose is what's throwing me off - keeps bucking me on the pop up / take off. My current board is a 7'8 Water Hog - same amount of volume as this board more or less (53L), but has a deep concave nose - almost like a noserider shape for a long board. Basically, the polar opposite shaped nose.
Never been on a board with a hull shape and a single fin. It's not a hull all the way through - just in the nose. Anyway - feels really different. On the handful of waves I was able to get up on - the waves were 2 ft - I took off going straight more or less - once it got up to speed it seemed like it clicked into form and worked great.
On bigger waves 3-4ft - where I would normally angle my takeoff on my 7'8" water hog - I couldn't get the rail to engage on this board and it would just slip out and away from my hands.
Any advice - should I be taking off straight on all waves - leaning further back? I'm sure after a few sessions I'll figure it out - but wondering if ya'll had experience on similar style boards.
thanks!
