I ran my 14 foot catarafts with a 66 wide NRS frame for many years. My set-up was similar to yours in the beginning. I rowed from a cross bar & seat, and had a large drop bag behind me for gear. I always had my cooler up front and can't recall any stalling problems with it being up front. I was always solo, so no passenger up front. Eventually I decided that I wanted dry boxes, and had Partner make two custom sized boxes for me. One 16 wide and one 14 wide. I had NRS make two skid guard floors for me. One for the captain's bay and one for the gear space between the large box that I rowed from and the small box in the back. The floor behind me, plus the drop bag, gave great support for gear bags. I used a AAA flip seat bracket that rested directly on the larger dry box to row from. The skid guard floors were super sturdy, with no flex at all. I attached them to the lower side rail of the frame with heavy duty cable ties and those babies wouldn't budge. They gave the structural support needed to off set the inherent flex of those NRS rails that I hated with a mesh floor. I can't tell from your picture whether you have a dry box in there somewhere? How are you feeling about the shorter depth of the lower side rails with the NRS sport frame? Looks like you have a solid set-up going on. Hopefully you will not be infected by the "tinkering bug" like I was and be changing stuff every season.
PS - I also used 9.5 ft oars
