Ok, looks like about as big as you'll find for a Cuban is a 56rg. Some examples below of things near that, that are readily available. The last 2 I have on hand, and the others could be procured without much effort. There's more variety if you want to get into special releases and what not. Play around with the search function on the site these link to if you want to see the full range. No guarantee a lot of the older releases are easily accessible, but I can certainly ask around if you wanted.
