really, if $ is no problem, get a series of private lessons from a good instructor and ask them if its time to up grade and to what.
yes your technique will improve over time....but how much time...good instruction can make the time shorter.
at you level of time on the hill, i doubt that you have developed a preference of your style or type of riding....and the hill...is very important and a huge influence (where do you ride?) that you ride has alot to do with that....thus your preference will determine the board...btw freeride, freestyle, park, jib, all mt fr, all mt fs, big mtn fr, big mt fs, twin, directional twin, camber, rocker, cam rock, shovel nose, pintail, rock/flat/cam, c2 vs c3, different types of mag, differences in sidecut and radius...etc. get familar with the different design tech...they are made for doing different things in different conditions. If you get a board...get one that is going to take you to your preference assuming you have the hill for it.
IMHO at this point, invest in more time on the hill and lessons
my 2 cents
