I almost always use KBB. It sounds like you are starting with way to much lit charcoal. I usually setup a 2x2 snake (2coals wide, 2 coals high) and start with 10-15 lit coals. I also use a water pan in on the charcoal grate and use hot water in it. Starting with 10-15 coals might take you a little bit to let the grill settle in and get up to temp, but its way easier than trying to cool down the grill if you start off too hot. With the snake method, I think the coals get baked enough before its their turn to light up which reduces the amount of dirty smoke you get. Usually on my 22's I run my snake with the top vent wide open and the bottom one barely cracked open. Also, if you are putting wood on your coals, make sure the wood chunks are not touching each other. The wood tends to burn faster than the coals and will cause you snake to advance too quickly. If you are using wood chips, the same thing applies, put your small piles of chips so that there is space between each pile.
