Can't speak to Rogue. You would fit in either XP. I'm 6'2" 180# and opted for the 10. I demoed both. My feet (11) did not fit the 9 with Keens/Chacos (which was not a huge factor, but i do like to have fairly strong shoes to shift easily to walking/hiking). Could be personal preference for you. I am used to touring and sea kayaks, so the 10' seemd short and maneuverable to me -- though very wide. I opted for the 10 largely because I wanted the option of growing into big water and thought the extra volume might help. I bet whitewater boaters of your size would prefer the smaller -- unless they needed the storage for self-support multi-day trips. I do love the boat. The cockpit of the 10 is very large, so be careful to get a skirt that fits.
