My current Grand Boise are the Hetre 42mm 650b and so far (2000 miles or so) I have had no flats and very little wear. I figure these will go 5000 miles on the back and ???? on the front. But they are a little heavier than most "performance" cyclists want to use.
As for new vs. old,
AFAIK the "old" ones were the white labels and haven't been available for quite some time -- several years, I think. The "new" ones are the green labels and what everyone has been using, myself included. If there are newer ones than that I am not aware of it, but what I am unaware of is a lot.
HTH!
4 or 5 flats in 200 miles is not the tire's fault. Perhaps a piece of glass was left embedded in the tire? Although Grand Bois tires are not particularly flat-proof, the lower pressure does help reduce flats. I rarely have flats on long rides with them.
