I use the Jack Brown Blues on my '91 Bridgestone RB-T for commuting.
Before that I ran the Supremes in 32mm and, before that.....Jack Brown
Blues.
I switched back to the Jacks because, like Brett, I found they were
smoother rolling but also faster on pavement than the Supremes. In
spite of them being wider.
When you roll a set of Supremes across a polished stone floor, they
rumble and you can feel it through your handlebars.
A couple folks replied that their experience was different and they
thought Supremes had it over Jacks.
Well....everybody to their own kick and I reckon there's no accounting
for taste.
But after back to back runs, I'm staying with Jack's in Blue.
