The other side of this, for me, was getting back on track with IFR skills. I never used the rating more than a handfull of times after I got it, and though I always kept current on paper so I could file in a pinch while aloft if I got into unexpected conditions, I was more than rusty. Then last fall I decided to go for my CFII and had to relearn everything. What a pain in the tail feathers! I spent over 20 hours getting back in the saddle. I've given 10-15 hours of dual for instrument work, and filed once for a simple flight in actual, but that's been it in the last two months since I got the rating. Next week I'm taking my Arrow on a trip from Illinois to Florida (assuming they get the damned annual done), and am quite intimidated about filing, should I have to... especially flying the last leg down the Florida coast to PMP. (Though to be realistic, that probably won't happen... if it's IFR weather, it will be due to storms, which will be a no-go anyway).
