To be honest mate there not a heap of bats out there that when you miss the middle will still travel. And even though id trust Talisman and SAF, if possible id reallly reccomend trying too go into Meulemans to have a look.
From everything ive heard and seen in Australia this year, Gray Nicolls have been by far the best brand of the year. Have a look at the Powerbow, and looking in your range , the 750 which Meulemans sell might be a go for you, or an Ignite 750. Also have a look at what you can in Puma in that range. If after all of that you cant find anything then feel free to contact one of the mentioned above, but as I said originally, I dont know a heap of bats where the balls going to fly when you dont middle it.
