"If sailing one up I would go with all options mentioned. make sure mast is above minimum weight and it is strong enough."
The alu mast die is widening a little due to frequent use and the newer batches of masts are slightly heavier, stronger and stiffer as a result. Basically, you won't have to worry about this aspect at all. The lighest masts held up great and it is impossible to expect the slightly heavier masts to be less durable.
