Maybe a 2023 FOIL X 145 an option?
A mate (heavyweight) of mine has loads of fun on that.
Dude is nimble like a ballerina on that thing.
And after years of intens use no signs of failing.

The downside of the 145 is that they don't have a center rear strap. I believe the 125 and lower do?

Thoughts on putting a mast track on a higher volume flat rocker wing board?

What wing boards are you looking at? Mast tracks are easy to install and easy to make strong enough. Ps I am watching this one closely because I only have one board ATM and I would rather buy an inexpensive spare today and take my time building a nice board over the winter. The RRD recommendation is interesting, there are none of the bigger ones in stock on this continent that I can find. Here is my current board and the RRD 200. I bet I could have fun with this; the tracks and mast tracks line up with my current design. The foot strap inserts are intended for use with the Tuttle, so for me I would need to add them if I wanted them, I am going to add them to my set up at some point soon.

The wing board I converted a year ago is still in perfect condition - original thread below.
Worth searching for one with obviously robust construction.
