There is no easy answer to your question - most of the sponsors no doubt could provide you with a blinding bat full of great performance! So that is not the issue!
If you know what kind of profile you like then that would be helpful!
Write down what weight you pefer, then kind of pickup, the middle position and the full spec of the kind of bat you're looking for - this will give you a checklist to go by! Your budget of 200 quid is enough to get you a superb bat!!
SAF do a fantastic bat, as do others on here. So it needs a decision you need to make. The last thing you need is for you to buy something else and still be thinking about that SAF Mechten you wanted!!!
So take your time and think carefully - you have a while until the season starts after all!
