Look at how many guys here still ride older GGs, that should say something.
I have a 2K-3 on the shelf I've been keeping for a spare. Originally I planned to swap it in and out of my '03 for various conditions but I really like the 2K-2 with either a 10 or 14 oz weight the best and have no desire to use the 2K-3. Its like brand new, came out of my '03 after a couple months. I may be willing to trade for a new/like new 2K-2, so if you get a bike with one and really need the 2K-3, no worries.
