The K-80 Parcours X has a lighter barrel with mid-rib and a stock that is straighter and a bit lighter than the #3/#7 Sporter stock resulting in a lighter weight K-80 with swing dynamics more similar to a Perazzi with mid-weight barrels. For a K-80 Sporter I enjoy a K-80 Gold Super Scroll with 32" Parcours barrels (1.39 K.G, or 3# 1oz.) and Parcours stock. The Parcours X barrels basically split the weight difference between the Parcours and Sporter barrels. Strongly suggest you shoot a Parcours X model with Parcours stock to see if you like the more dynamic swing characteristics. I found I preferred the even lighter Parcours because I have been accustomed to an MX8 with 1.55 KG barrels. Switching from a 32" Sporter to a 32" Parcours is quite significant and Parcours X might be a better fit (or maybe not), so, shoot both the Parcours and Parcours X to verify what works best for you. Don't forget to shoot both with the newer Parcours wood set, as I believe you may prefer it to the #3/#7 Sporter wood. Good luck.
