Yes Optisplitstick solid alternative

Looking for a solid alternative that rides like the yes optisplitstick.

For context I love riding off piste, in trees and powder where I can find it so need a board that is super nimble, easy to turn, floats / surfy in powder. I like volume shifted boards as I have US12 feet so that gives me the width I need whilst staying nimble.

I have various snowboards incl Yes Greats (my absolute go to board for icy conditions - can’t beat it), Capita Mega Death (great board for charging but not as good / nimble for trees etc), Korua Dart (just sized down to a 160 on this one as I didn’t find the 164 plus nimble enough in tight trees so don’t have a definitive view on it yet), and then I have a Yes optisplitstick.

I’m finding myself reaching for the split almost 90% of the time when conditions are good no matter where I ride incl in resort. It is just that good. But I don’t want to use my touring gear all the time so am looking for a ride that is basically the optisplitstick in a solid. Yes I’m aware there is a solid version optimistic but it has a 9/10 flex whereas the split rides like it has a lot more flex (say 6/10) due to being a split., making it super fun to ride.

So I’m basically looking for a solid optisplitstick or an optimistic with a say 6/10 flex.

Any ideas? What’s the closest alternative you can think of? Ideally volume shifted? K2 excavator? Hovercraft 2.0?

For reference I am 187cm, 87kgs and US12 boots. I’m also 53 yrs old but that’s not holding me back 🤣.
