thanks for your wise word guys.
I had a look and play with a 10" dob and found it to be very easy to manipulate and quite steady when using the bump/steer method i.e. hands off as much as possible (head is nice and steady

)
So...I'll focus on a steering/bumping technique that works for me and ensure I get the value of more aperture (I ended up buying the 10" scope)
Will also pull my thumb out and learn the sky, starting with the simple / easy to get to things and working my way up. My phone has a good gps/compass etc. in it that works extremely well with those virtual sky apps and I picked up a sky and space magazine today.
