I know this is old but for posterity purposes, after I removed my curves from the Tomcat and added a little saturation so I only have 90% max input, my tomcat problems went away. This sounds counter-intuitive as I'm sure you wanted to deaden someof the input, but curves give the F-14 the opposite effect somewhere towards the middle of stick travel. The Tomcat and some warbirds are the only aircraft I highly recommend NOT using curves with strongly suggest to learn to fly it without. The issue with the curves is that it becomes wayyyyyy to easy to buck the plane now because it's too easy to hit that input speed ramp. Small inputs are easier, but the sweet-spot is now smaller, and it actually becomes too easy to over-control the plane now and make her shake n quake and come apart.
I couldn't do an on-speed case-one trap for the life of me until I took the curves off. Practiced for 12 hours straight on one Sunday, failed all but 1 lucky attempt that I did (the gamer way), and then the following day took the curves off and had no problem.
My other tip is to only adjust your trim on downwind leg only and not touch it after that. From then on out use the DLC wheel/stick as that will practically turn the E bracket into a cursor that you can slide up or down to control your altitude/flight path. If you need more time to trim out, make your initial break later so you have a longer downwind leg. I find that with all my wings, boarrds, flaps, dlc, gear extended that she flies level and onspeed with throttles at or about the MIL line.
