O and I'm going to be doing a little of everything but not really too many rails or boxes, mostly jumps, spins, trees, groomers, slack-country. So with that in mind, would the 390 boss's even be a contender ?
The 390's are softer than I would want on a Heritage. If you want a good do everything Rome binding I would go with Targas. I have Diodes on my Heritage (which I love) but they are not really a do a little of everything binding. YMMV.
