As a big fan of GM I must say they have massively improved from the off over the last few years. However I still net with mine against bola balls for a good 6/8 hours at least so I know it’s fully match ready. Mainly because I don’t have the time or patience to make all the noise with a mallet plus I really like getting used to feel of my new match bat
Handy if you have a bowling machine free of charge
