PearlPilot - Your ideas are all kind of what I had in mind. I've done the same thing picking random airports on the sectional. Flying IFR plans in VFR conditions will get me more used to talking to center and approach. Or at least request flight following. I have a few hours of actual which I really had fun with. Shot an ILS nearly to minimums one morning with my instructor. I'm honestly still somewhat intimidated by class B, but I feel like there's really no better time... I am working on a commercial rating after all. My instructor said he would go actual with me anytime, but those are expensive hours. Probably the best experience I can get at this point though.
Thanks for the replies.
Oh and I've done 95% of my flying in the 150. I believe if you can shoot an ILS on a windy day in an old 150, you can shoot one in anything. Really is a good airplane but anytime I get the chance for more room and power the choice is easy haha.
