@Justino I was able to order a 9.5" Involvement this morning. They have them in Black, Red and G10. They are all out of clear volan. The owner, Mark, explained that the G10 is a really stiff fin and that CJ uses it in heavier waves. Someone else had explained that the they used the volan in choppier surf and the G10 in glassy lined up surf. Mark mentioned he really likes the G10 and surfs it in everything. I opted for the Black fin since I probably won't notice the difference and I don't surf big waves or with all that much power.
