I hear you.
Have built a bunch of boards over "a few" years since first learning to arrive at a couple I like.
Would have been easier/cheaper to just buy another good board or two,
especially before I had experience. The first couple I made were not that great, but it was fun.
If you think making bindings too will be fun, go for it.
I found it was a pain and the results did not compare to what I could buy.
Yes, it's possible but...
...maybe I just didn't put enough time into it.
Anyway, sliding into my liquid force straps is a "luxury" I can't duplicate at home.
Enjoy your build!
