Ruby Pommelo ripe?

[Tropheus76]

Hey I have one on my tree. When are they ripe? I think I waited too long last time and after I cracked through the 2" rind(serious if you havent tried opening one yet) I found it to be extremely stringy and not very good. They current one is a little bigger than a softball and light yellow/green.

In Florida,  in general,  pomelo season is December thru April however with all citrus, they sweeten and flavor up after the weather cools.  I am not familiar with the Ruby variety however what I have had have been best between January and March.
