Re: Blocks and bells....
Here is a suggestion to consider that is a different direction. What about one or two Roland BT-1s and a sound module? Acoustic blocks, cowbells, etc do not have a lot of projection, plus you always need that one other piece of percussion, be it variation of the bells, finger snaps, hand claps, tambourine, castanets, etc. I know the acoustics are better, especially if you are a pure percussionist, but samples today are really good and you can easily make your own samples as well. This route does take some getting used to though. Just some food for thought.
