Had one local copilot, when it was his flying sector, seemed to prefer to do the visual approaches slow, and the instrument letdowns fast - probably to get them out of the way, and get out of the cloud, and on the ground quicker. Prefer to do them the other way round, to ensure getting down to the minima with time to get visual for landing off the first approach. Re-used half drums of fuel in humid areas will be more likely to have condensed water - check well on use.
