I'm far from any kind of expert on this, but I've dabbled in it and made my own for the last 3 years.

I typically use the standard size frame- which they call the 'small' frame and the appropriate tape for that frame in the color of your choice. I've had some of the bright colors taste about like battery acid, so be wary of that, maybe his won't.

I typically use proph, .0025, and .003 latex for my calls. I find I can run them easier with thin material and only 2-3 reeds.

Tension- who knows? I used to stretch some at .200 and kept dropping it down over the years. I usually stretch mine to .140-.150 now if I remember correctly.

Hope some of this helps!
