Ahhh good question, i pretty much rode mervin till this year when i switched to a berzerker and i am so fucken sold on their hybrid shape, i seriously looked into getting the highlife and making a DIY swallow tail like you did.
Since i dont believe they come any bigger than a 171 i figured it wasnt worth doing that. SO anyways in answer to the question i was kinda hoping flat based or slight camber, i think i might be done with rocker. But could look into hybrids also
Both these priors come in a 178 and have camber with an awesome rocker nose profile, they will absolutely destroy it in japan for you. I would love to own them both and cut swallowtails in them lol.
