I've just moved from flying an Archer to C172s recently and I'm very glad that I don't have the misfortune of having to change tanks anymore. One of the scariest moments I've had would have been watching the fuel pressure slowly trickle down after swapping tanks just after take off from Goulburn.
However, on the other hand, fuel management awareness can dimish seeing that you don't have to monitor which tank you've been on and for how long. Never really did like the idea of "set and forget".
