sorry, almost forgot, the barrel lenght is a non issue as well, atleast in my experience. For the most part, a longer barrel only serves the purpose of adding weight up front to allow a more steady and controlled follow through-typical of clays and wingshooting. Most squirrels (while some are shot scurrying across limbs) are shot while sitting still as are deer. Some people even prefer the shorter barrels, 26" and 24" in the woods as they claim that the extra 2 or 4 inches can get hung up on brush.

Hope this helps
