I have rocker panel blasters as you enter my IBA which are basically pipes that stand off the floor approx 18 " tall. I also have the undercarriage which runs with the sideblasters. I currently use regular 0504 IMEG tips in the sideblasters. I was wondering if it is worth the extra money to change the rocker blaster tips out to zero degree turbo nozzles? A local carwash operator told me he had so much trouble with the turbo nozzles if he had it to do over again he wouldn't use them. Just wanted to get some other opinions.
