tune smart go smokeless what fun would that be??? i am still using my diablo sport predator and i love the smoke. i recently got a letter in the mail from the az dept of air quality someone actually took the time to write my lic plate# down and call them and make a complaint and they took the the time and effort to write a letter and spend postage to send it to me. people never seem to amaze they obviously dont have enough problems in their own lifes , they have plenty of time to worry about what others are doing. me personaly i am way to busy trying to keep things straight and take of my wife and 5 kids to worry about what other people are doing, sorry if this seems bitchie just on a rant.
