Ok for those of us in the U.S. I found a great smoke fluid that REALLY smokes up a storm! Mega Steam, its made for model railroads but will work in any smoke unit and won't damage them or at least thats the claims. I ordered a small bottle to give it a try and put it in the stock H/L and Taigen smoke units and MAN they REALLY pumped out some smoke! Well today my replacement Super Smoker II got here and after it's initial use with the smoke fluid it comes with I put in some Mega Steam smoke fluid and took the Tiger out for a spin and WOW did that thing smoke like CRAZY!
Even at idle the smoke coming out is very thick and as soon as I throttle up the smoke POURS out of the mufflers to the point where it damn near hides the tanks rear in a smoke cloud! I got the non scented version which actually smells like burning birthday candles I may try different scents next time but for now this stuff works great!
All in all I'm VERY happy with how the exhaust smoke has turned out for my Tiger.
Now for my King Tiger I may try to build an acoustic smoker, but this smoke fluid is the stuff I'll be using thats for sure.
