At 30ft and 9400# you could be exceeding the 1400# max on the Hensley and Propride anyway. I'm at 1350# TW with a 32ft and 8500#. I've had several threads concerning my Reese Dual Cam as well as the HA and PP in regards to tongue weight.
The DC can be a complete PITA to dial in. I set it up on my old combo perfect the first time. This one has taken a trip to Fla. and back before I got it right. I would HIGHLY recommend going to a scale and finding your tongue weight before you buy any hitch. I had 1200# spring bars that I thought were more than adequate for my trailer, but wasn't.
There are some real DC pros on here than can help get it dialed in, if you go that route.
