Cricket bats are the one thing that I'm not overly picky on...
Somewhere between 2'9 and 2'12, lower middle although my Hunts County middle is about mid-way, don't care about grains. My GN Venom Viper has 6 grains on, my County has 16... Erm... Fairly decent pick-up? As long as it's fairly decent value for money, it's fine by me! I have both Oval and Round handled bats, concaving really means nothing to me as well. I have one bat with heartwood, one without, and it makes no difference for me!
