Good fightstick recommendations for larger people.

Jumped back into fighting games and I for some reason no matter what cannot get my execution down. Part is my rust but part is also seems to be due to how scrunched up my arms can be at times making it slightly physically uncomfortable as well along with the constant concern of my arcade stick being a tad loose to my liking.

So what I would like to ask is, if a larger person wanted to get something slightly above 18inches (came up with the number due to that being the biggest size in allfightsticks) and would using a Korean lever on 2d fighting games help at all?
