I just logged in so excuse me if this first post brakes any rules of conduct here

So on to my question.
I have done skiing since i was a kid, switched to snowboarding close to 12 years ago.
Although being tall (2m) and pretty heavy i aquired a resonable level of skill in snowboarding, pretty big jumps, butter tricks, freeride, grabs, solid carves on regular boards and so on.
But lately (through long years of weight traning) i got really, really heavy (132kg atm. not fat, mostly muscle), and decided that if I want to continue snoboarding big hops and stuff i out of the question.
So.. since gravity really accelerates me FAST i decided that carving will give me the rush and control I am looking for.
The problem is that all the equipment i use for regular snowboarding is usually, special, big guy stuff, stiff shoes, big board (lib tech skunk ape).
So after this lengthy beginning, my guestion is, where do i get started? Going stiff set or regular shoes at first?
Stiff bindings?
What about board length and width, are regular models going to fit me?
I would also very much appreciate budget options if You can

Thank You in advance for all Your help!
