I was in a similar position as you with my RN SJ. I had the basic bolt on's for the 701 and decided the next upgrade was hull. I went with the Vision from WCF and I'm really happy with it. Cutting a bunch of weight made the motor feel a ton stronger, and I love the stability and maneuverability of my new setup. The hard part is there are so many great choices out there in hulls right now it makes it a tough decision!
