binder recommendations?

hello! i’m a fairly skinny trans guy but recently i’ve gained weight (which im very happy with) but it means my binders no longer fit comfortably. i usually wear a size M or S, and i think a large will be too big on me.
my first binder was a GC2B binder that worked okay, but i’ve heard their quality has gone significantly downhill. spectrum binders are too loose and don’t bind enough for my liking while wonababi are too tight and hard to breathe in, so im looking for a middle ground. any recommendations?
