Good point - GS dont go red - Take that reference to refer to the taste
then, rather than the color!

Cheers for the advice on pruning - very valuable - We do have a LOT of
newish vertical growth which has just gone straight up from a certain
point, and thats what I hope to tackle.

The tree does seem to be in good condition otherwise however - LOTS of
fruit, and no dead wood that i can see. Altho it did get hit by some
sort of burrowing pest this year.
