VFR "on top"
In this neck of the woods it's perfectly legal to do so, the only stipulation is that you have a cloudbase of at least 1000ft GND and you are 1000ft above tops and that you have managed to get there VFR/VMC and can get back down again VFR/VMC single or twin.
Let VFR pilots "loose" on top, bit strong methinks. I've done it loads of times, beautiful weather on top (8/8 blue), smooth as a duck pond, favourable winds etc.
BUT!! I've always checked my weather VERY carefully and made sure that my alternate is clear and that I have more than one option IF it should clag in en-route at any time.
