Just as another data point and of zero statistical significance, I had a couple of Triumphs with Monoblocs and concentrics and had a GP on a Goldie, and never had chokes (air slides) in them. Always tickled the carbs first. They don't run right unless you have at least one gas soaked thumb or finger. It's the way they were designed. And that was in Scotland where it gets pretty cold - not Chicago cold but cold enough...
Other people like the air slides. To me they were a waste of space and another thing to go wrong, but it's really a personal preference.
