One thought you should keep in mind too is your height and where the pole mounts to on the Chan. Most A/M hulls move the mounting bracket forward more by comparison to the SuperJet. So if you were running a stock length pole in the SJ, then you might as well consider the pole as a -2 or -4, however further forward the bracket is by comparison to the SJ. I like the SJ stock length for my KP pole as I am about average height at 5'6. I find the stock length doesn't require me to lean forward stressing my lower back...and after a vicious car wreck a few years ago, less stress on the lower back is mandatory for me. I did also find that going to a -2 stock pole worked out quite well when the stock pole wore out and needed cutting down. Keeping that in mind, if the Chan bracket is moved forward more by default, a SJ stock length KP pole might be preferential, as you have noted too, you can always cut it down as needed to suit your preference. Just keep the cutoffs to act as spacers if you cut it too short, there is lots of clamping on these KP poles so I would assume using spacers will not negatively affect clamping capability.
