Qick change tool post. 12inch lathe

finaly got my lathe sorted out abd been playing around with it. Now i want a qctp for it. Ive done a bit of searching and want opinions on which would be better. The axa or bxa. Ive been recomended the bxa because it holds larger tools. But would it be big? Perhaps get in the way of the swing and/or tailstock?

Thanks
