These two racquets are very different. Once you know your play style, it is not difficult to choose (a more difficult decision is to choose between Ti-10 and Ti SP SX).
Fyi, Ti-10 cost ~HK$100 less than Ti SP in Hong Kong.
p.s. Cab 23 is a very powerful racquet for those Carbonex lovers, however it seems that it is not durable. Mine was broken recently, and I've used it for less than 10 times. There was no hard hit for the racquet, and it broke when the string was broken the 1st time - after I cut the string, I found that the upper part of the frame was broken.
