not really that much different from a 3-row (but a good bit lighter)... and you get less options as far as key changes.

I really like my 2-rows, especially since they seem "hotter"than a 3 row tex mex 2 reed because they are easier to pump.

I have never played a corso... a 3 sets of reeds 2-row, but would like to see how ballsy it is.

Two row Corsos are very ballsy.. John Delafose was rumoured to have played one at one time..and there once was posted here mention of a video of him playing a Corso.
