In that case, you will want to swap your pole from the older superjet, because even tho the 08 is shortened -2" compared to the older sj's, it is still a FX1 pole and uses a FX1 cable. These poles only accomodate the shorter, 2.5" throw FX1 cable which just plain sucks. The older superjet cables carry a full 4" throw which really helps alot with the steering.
If you decide to keep the 08 pole for whatever reason, you would need to order a shmity1 kit which uses his one-off cable and mounting bracket. Replacement cables can be difficult to find in the future in case you ever need one and his shipping wasn't too fast.. ATM im looking at aftermarket handlepoles, and now im gonna need another 96-07 steering cable because shmity's wont work. It sucks to buy things twice.
I also forgot to mention another point about the 08 handling. At mid speed and high speed the hull likes to chine walk, and kind of shake from one side to the other slightly. Coming off of my Kawi I noticed this right away, but after getting used to it, I dont feel it anymore. Others pointed this out too, but I think it has to do with the narrower rear and balance. Like hopping on to a long board for the first time.
