I haven't personally used a Torch or a Boxer, but I have found that the Naish Aero II (the 2002/2003 model) to be a wonderufl kite despite its' age... I would suggest Steve or one of the guys that would know about these kites to comment on their performance and what would suit you the best.
However, it might be of interest that the Naish Boxer II 9m is $1099... Big difference in price if the Boxer would suit your needs and style... For the $700 you save, you could get a new board

... All the best mate -Hope I could help... Feel free to give me a buzz anytime
