try joystick curves, it may work for you. it didn't for me. i couldn't get used to the random change in response. i guess it depends on your flight style and if i had persevered it could have worked but i never really liked it and in the end ditched the idea.
i now use the stick as is, and help out with vertical/lateral thrusters and faoff, that's it, and i'm pretty comfortable. my aim is average.
gimballs enable you to easily apply all the dps you can generate ... to a target that doesn't use countermeasures properly. that's not how 'real' combat works. while you can do fine in pve, gimballs will not hit even once a cmdr using double chaff or gone silent, unless you get really really close.
fixed is not as efficient for grinding (shooting ducks) but more versatile in any other situation, and also shines at long range. practice pve with fixed and you'll make less credits but the improvement in skill will pay off, and is a far better reward imo. actually, i've spent lots of hours practicing in cz and res and made a lot of money in the process, but it wasn't a grind to me, it was just learning and training, quite fun and i even got paid for it!
