I`m a year past my PPL now and had 25 hours flying after getting the licence, I found myself with an 8 week gap during the summer (due to holidays, bad weather etc).
There was no way after that 8 week gap that I`d have gone up without an instructor, I just wanted to be sure that there were no bad habits that had crept in.
My solution turned out to be to start IMC training. In reality, there were no issues at all with my flying after the gap, everything fitted into place fine.
What I have found though that with 5 hours IMC training so far that my skill and confidence have come on leaps and bounds, its really given me a whole new view on it all.
