rare whistles – how many to collect ??

here is another thought to help in 'thinking shrink'

You can't shrink what you don't have !!

So you have to have enough collected to cut your collection back….Der !!!

In other words a collection has to grow first. THEN look at what to weed out, refine or even change.

—- another quote from the computer world…."Simple designs often come after the project has been running for a while".

Gotta have not just whistles, but knowledge, then rational decisions can be made. Sure there may be a dollar loss, but that comes with the territory of education. Like paying for a class, only a LOT cheaper if thoughtful about what is purchased.

Yeah, you might kick yourself for taking a class you don't like, but who knows what will be learned after all ??
