I like the 24 inch tapered, the 26 inch heavy and the 28 inch Pro Hunter Barrels. Oh, and I also like the 12, 13, 14 and 15 inch ones. Isn't that helpful?
Seriously, judging from the numbers of Pro Hunter barrels coming on the market at very good prices, I believe a lot of people don't like the 28 inch length once they've tried it but I do.
