Been then, done that (bough a T-shirt)... Collecting styles is extremely tempting for many arranger owners and when we see a post "here you can download my very special styles" then it's hard to resist: what if there are some really good ones? There's a basic thinking, that one just can't have too many styles (we never know when we may need some of them).
And so we start comparing them, delete a few and then we sort them (using whatever method), so we can find them easier later. This process repeats every time we see "here's a link for download..." and every time we do that, we get less and less styles worth having.
However, the time that we spend for that increases every time! -because we need to compare new stuff with existing (growing) collection. Not to mention, that after a while we usually realize that our sorting method wasn't really that good and so we need to reorganize everything from bottom up.
And finally, it happens very often that when we need a style for a song that we wish to learn, we won't find it in our collection.
What a waste of time... It's just my personal experience.
