2018 Boxxer RC (coil) or 2019 Boxxer RC (air) for heavy rider?

I am choosing between a 2018 and a 2019 Kona Operator for a bike park bike.

The 2018 Operator has a coil sprung 2018 Boxxer RC while the 2019 Operator has a new 2019 Boxxer RC which is air sprung.

I am 6'3" and 290 lbs in riding gear. May get down to 260 lbs over the winter but not lower than that. I am riding bike parks for fun, and definitely like to jump. I'm more of a set-it-and-forget-it -kind of rider at this point, so tunability is not my highest priority.

I would prefer a coil-sprung fork but am not sure if the Extra Firm spring will be enough. According to the Rockshox spring chart, it's not (the Extra Firm weight figure stops at 225 lbs) but then again there are comments that the Rockshox spring chart is excessive, meaning people usually run a lighter spring than specc'ed by Rockshox. I realize the Extra Firm spring won't just collapse at 226 lbs, but I am concerned about bottoming out on bigger hits.

The 2019 Boxxer RC with its air spring would provide more tunability but since I have no experience with air forks, my concern is that I'd need to run high pressures, maybe losing that tunability and not getting even close to a coil-spring feel.

So:
1) Anyone out there in my weight range with a coil sprung Boxxer?
2) Anyone out there in my weight range with an air sprung Boxxer?

In essence, which one would you get?

Only 210 with riding gear on. 2017 Boxxer RC and I was supposed to run the firm spring but I couldn’t get full travel out of it. Medium and bottomed out too much. I converted it to air and I’m much happier. Using the travel the way I want. I like the extra pop on the jump trails too. The motion control damper sucks big time...

We have a progressive Boxxer spring which is a rate above the stock Rockshox black spring, possible solution if you wanted to run coil.

Does the 2018 Boxxer RC still have motion control damping? If so i'dgo without a doubt with the newer version, wich uses a charger damper. Motion control on the boxxer RC is a joke.

The 2018 Boxxer RC has the same chassis as the World Cup and Team model, but with a not so great damper (Motion Control IS ). So if you have the damper replaced with a RS Charger, or even better, an after market one like from Avalanche of Fast Suspension it will be a top performing fork, especially if you have the damper tuned for your weight.

A 2018 boxxer can also relatively easy be converted from an air to coil spring. The other way around can be done too, but if the coils have scratched the inside of the fork there is a chance it will leak air.

Not that this will really answer your question but...

I've run both the air and coil versions of the Boxxers and much prefer not only the feel of the coil but also coli for durability. Nothing but trouble from the air spring, but maybe they've improved over the last few years.

A stock coil at your weight may not work but the guys at Race Only Springs were great to deal with when I contacted them. I ended up going to a different damper instead of a progressive spring, but it was a close call.

I think both RC forks come with the CroMo damper which I hear is not so great. But at your weight any stock damper is liklely going to not work well.

All that likely didn't help, but some more to think about.

I agree that your best option would be coil with damper tuned for your weight and riding style. I'll be getting an Avalanche damper for my 2017 RC for next season.
