I think the new Makos are definitely ‘poppier’ than the old ones, however they are obviously not on the same level for pop as a freestyle board like the JT Pro. I personally rode a Grom 130*35 this summer, and then promptly bought one fairly soon after that! Personally I ride winds similar to yours, and am about 135 lbs, so not too different.
I find the 130*35 to be fantastic. I had an original 2007 150*34 ‘Classic’ that I really liked, but at my size it was just a bit big, especially in the air and through fast turns. I find with its smaller size I can really drive it into a pop hard, and it seems to work surprisingly well for its shape.
I have limited experience with the 140, but for me it still felt a bit big. I think it would be a great freeride board for someone a little heavier than us (maybe around 180+) but I just couldn’t drive it as hard as the 130.
My 2 cents would be to go for the Grom if you want to maintain that carvy feel of your Mako Pro and gain some pop. If you want to really get into the freestyle, then you’ll probably want a dedicated freestyle board.
Hope that helps!
