I don't have a vmar but I do have an ultra stick and I think either engine would be fine. Make sure you put extra epoxy on the firewall and the wing hold down. I agree that you should make a taildragger once you learn to take off and land a taildragger you will never go back to a trike. I have found that it is much easier to take off with a tail dragger because as soon as you get a little speed it will track much better than trying to fight with a nosewheel taking you from one side of the runway to the other. Good luck with it.
