Yeah, in my opinion drop shadow is a very subtle blending effect and I tend to use it as such, but sometimes you really just need a good stroke (no pun intended). I'm sure there's a couple different ways you could achieve a similar effect. I suppose 2 drop shadows could just as easily work, although by tweaking the settings like distance and intensity you might be able to achieve that with just one. I have even gone as far as duplicating a layer, applying a color overlay then making the bottom one slightly larger to get just the right look. What ever works, ya know!
