Well I'll start off by saying that I'd echo just about everything you say.
The differences from GA are certainly significant. For example I trained at a school whose focus was on the CPL, so I was taught firm arrivals were the preference to floaty full stall ones. So I had to learn to round out, hold off and hold off and hold off......and so on. The rudder is still a source of entertainment; bear in mind that I did some soaring in between GA and LSA, and I quite expected to be overusing the rudder as a result. No, that bloody ball has a mind of its own and I frequently find myself in a cruising side slip, giving Gordon a better view of the ground than perhaps he wants. Whilst not the full blown US style tundra tyres, they are rather like oversize wheelbarrow tyres and may well be doing as you suggest.
Operating out of largely unformed strips is quite an experience too. Many years ago I flew in and out of Ipswich (UK) a few times. A grass airfield, it was situated next door to the factory of Arthur Ransome - at the time the leading manufacturer of domestic and commercial lawn mowers, they used the airfield as a test ground and it was an absolutely superb surface that I'm sure would have Gordon rolling in the throes of orgasm!
In all, the LS version with the 600kg MTOW its a very practical aeroplane, allowing two persons, overnight baggage and close to full fuel. It's way better than a C150 in many ways, including cabin space and uses a fair bit less fuel.
I did stay up a couple of nights, but still only managed to get about 7 hours in, so I have a few days scheduled over the holiday break that will hopefully allow me to finish off what I need to do.
