vee to single to double to vee ?

For those of you who use a shallow rolled vee in the entry to flat to the wide point into a single to double concave with some vee out the tail (sounds complicated I know), do you flatten the tail vee behind the back fin like you would with a more forward vee that peaks in front of the front fins?

N.N. If you want the board to roll over more in the turns and the water to spill off the back of the board freely let the concaves die at the trailing edge of the fins. If you want the board to feel very drivey and the tail to grab then keep the concave alive in the vee’d exit. The more concave you hold in the the tail the more lift it will have. It’s all a matter of how you want the board to act and the conditions you’ll be in. Good Surfin’, Rich
