I suggest you learn to butter. Buttering is not "leaning". You have to use muscles to press and butter.
Closest thing you'll get to something that is awesome on both jumps and rails is an Arbor Wetmark, Flow Verve, Signal Park Flat, or a Salomon Drift rocker. But none of those are going to be easier to press than a Banana. But they are all better boards overall.
You talk about the flow verve which I am very much interested in. I am looking for a park board or more so for kickers. I already have a ride machete. am I going to notice much difference going with the flow or a NS evo. I do need a replacement the machete is badly damaged.
