I would steer you more towards the thinner side of the midfats, more in the 74-76 range. This will give you a ski that has more usable sidecut and still perform very well off piste. The pocket rocket is on the soft side wiht a radius of 20 M or so. Drop down to between 12-15 and you have a ski that is more versatile, a ski that you can learn in all enviroments, and will still perform well off piste. I personally like plenty of sidecut untill it gets deep, like 18-24" plus, then I'll go wide. Even though I can handiliy ski my mentrons in any depth.
In the atomic line I would look at mid level mentrons and lower end daddys. solomon, rossignol, k2, ect., all make good skis in this category. so my advice would be rather than to have a model in mind for youself I would suggest looking into demoing from a category, and price range. At your level, I would suggest mid level one ski quiver skis to demo. Later, RicB.
