Mazzy - two separate VORs (and an ADF thrown in for good measure). Using the two VORs I found it useful to track out on one radial then intercept the other from VOR2 at the right place. A check on the VFR chart shows that I am where I'm supposed to be.
Of course, I'm still flying VFR all the time and aware of position but this makes for a great introduction for using radio nav aids and it all makes much more sense in the air when you can see what is happening in real time. What did help though was a wet and miserable day where I sat in the aircraft with the instructor and we tuned into VORs on the ground, identified them and then turned the heading dials. Once I had this knowledge it made things easier to follow in the air - I'd recommend it if you are located near enough to VORs or NDBs to be able to do some ground based practice.
The other fun I have is to use the VORs to practice my estimating skills for angles. I'll use my current position as a 'diversion' point and estimate the angles to the VOR ground stations as though they were airfields. Then turn the VOR dial until the radial is locked in - and compare notes with my earlier estimations.
All this tuning and reading of books on DME radial turns etc. has really given me an appetite for the IMC once the PPL is in the bag.
