Used a Gray Nics Xiphos Pro Performance, which formerly belonged to Steven Mullaney, but was left in his locker when he moved from Lancs, and so one of his team mates nicked it, and has given it to one of my team mates.
My team mate let me have a bash with it at nets.
Pick up was lovely, and it was a chunky piece of wood. No scales or anything, but guesses are weight was about 2.8oz.
....but other than that, bit of a plank. We had an open net, so got chance to see how far the ball could go. Played one nice cover drive, which wasn't quite middle - felt horrible. Wasn't forgiving at all.
So I guess Pro bats aren't always what they're cracked up to be (ceraintly the ones the pro's are prepared to give away/leave behind!)
