Squash dilemma

I need to tap into the Gardening UK hive mind!

I have a very large homegrown musquee left which I picked while still green in November ish. From memory it formed later in the summer than the other squashes. Its turning orange at a glacial pace. Should I:

a) use it now? Worry is that it won't be ready?

b) wait for it to turn orange? Worry is that it will rot before this happens?

Thanks in advance!
