My college roommate got me into duck hunting, which for us meant wading marshes and rivers. I reasoned, when up to your ass in muck or current, it would be easier to keep the muzzles of a sxs out of the drink because the break open angle was half that of my o/u. That was my justification for buying a Flues. Then I learned a Flues shouldnt be fed Walmart duck loads so it was back to the o/u.
