OK- here goes...
The 99-00 (prototypes and early retail production)/00-01 Mod X/ MOD X PRO are essentially the same skis as the 01-02 AXIS X/ AXIS X PRO. The differences were the removal of the chip (due to contractual hassles w/ ACT, the manufacturer), and a graphics change.
Yes, there were material problems with the earliest version of the MOD series, resulting in cracking (as was discussed) but that problem was pretty much resolved prior to the 00-01 model.
The current (02-03) version of the AXIS X is virtually unchanged, except for a bit of rounding of the tail (as Gonz stated). OTOH, the AXIS X Pro, has changed significantly. Though it has kept it's same general construction, it has become much wider throughout it's length. Still a very balanced ski, it will provide more stability off-piste.
The greatest changes in our 02-03 line ocurred in the MACH S/ MACH G. Now called the AXIS XR, it keeps the construction of the MACH S, but by altering the side cut, and lengths, it now serves what K2 believes is a more dynamic purpose. It blends the snappy carving S with the stability and dampness of the G together in one ripping ski. For those who prefer a metal laminate, hard snow, carving ski, this is the one.
If you've got any more questions, just ask...
(Yes, I do work for K2...)
