Funny you should say that I was taught by my schools cfi and on the 152 my power setting is 22rpm told to never bother leaning!
Can't mention school though for obvious reasons
Thanks for the tips though, so do you think it's worth while? To be honest my family don't really like it so most of the time it would be me on my own with the occasional friend coming up, I'm thinking on longer journeys it could be done a bit faster and the weight issue would be less of a concern In a pa28(I'm no stick insect)
