I concur. Risers too tall. Here is a picture of mine, it works pretty good.
a 1 inch ball valve on the front, 1/2 inch cap and nipple at 3 & 9 o'clock, and a 3/4 inch cap and nipple on the rear. Usually I leave one 1/2 inch nipple open and adjust accordingly with the ball valve..
UDS, Mini-UDS, smokey joe, gasser, 3 pie irons, and a weenie fork.
