re QCTP's

question for the learned , i have a cq6230 lathe ( or al400 equiv ) it has a 12" swing i would like to get a qctp for it from what i can see i can use either an AXA or a BXA with the axa it is on its limits cos it does up to 12 " swing , the bxa does 10 to 15" swing so what would be the better option get the axa or would there be an advantage having the bxa . never having used one at all i cant tell , would the bxa be a lot bulkier ( is that a word ) and or would the axa flex more ????.

thanks
