I run Ikons front and rear all over the southeast including the gnarly stuff in Pisgah. They are the perfect tire for FATS. I'm running 29s tubeless and I run 24psi front and 25 rear pretty much everywhere. I weigh 170.
The ardent is overkill and heavy for the constant accelerations. I've been using a Rocket Ron up front with an Ikon in the back for several years now with great luck. I'm going to replace the RR with a 2.4 IKON up front to see how it goes. Going tubeless may by the biggest benefit 'round here as it improved traction on the sometimes slick/hard packed surfaces.
All that said, watch the weather. It's been the worst weather year ever here and, normally expected good fall weather, is not guaranteed. Some of trails are pretty rutted and a little extra bite could be good. Also check Sorba-CSRA for hunting closures etc.
