Bingofuel suggests that passengers may be made uncomfortable if you weave to maintain viz; they'll be even more uncomfortable if you hit another aircraft.
Seems to me there are two questions here. Climbing out of an airfield, yes, lower the nose to check you are on runway heading, and do this several times. If your climb rate is truly nose up and your performance like in my supercub, remember that in Britain they have curious ways of joining overhead!
As for climbing enroute, weaving is much better for notifying other aircraft of your existence.
As for using clouds for reference, the only one that's guaranteed to stay in one place is the lenticular - unless of course the wind changes.....
Otherwise, by the time you dive back down through the hole, if your GPS has gone up the Swanee, you may find yourself out over the North Sea.....in which case best to radio Aberdeen and ask for help please.
