Rolled my own when I smoked.
Yep, my view is 'let the market decide'. Especially WRT bars; I know of bars that had business pick up after the smoking ban in SanFrancisco; my wife's friend said she could stand to go out again, OTOH since my band gets paid a percentage of the bar I'm torn, my equipment and lungs age faster but smokers are often heavier drinkers, which is good for the bottom line......
Sounds to me like you'd rather not play in smoke filled bars, but if the money is right you will. Sort of like being a tech rep in Iraq..
