Got inspired by this and another similar design version that I can't locate just now. Both were set up for playing multiple picks on both the up and downstroke. I thought that made it too thick and harder to get between desired strings if wanting to not be strumming all of them. Got nearly the same sound with just 3 of the plectrums. Does mean that it only works for the complicated sound in one direction and best used for a down stroke. Thinner made it easier to do selected strings or groups of strings.
