Al, the second one (style) looks excellent for string lining or hanging beavers. However I fear if the first style was used in lieu of a barrel it may get trashed

. I have seen what they do to steel drums!!! Then again maybe the accessiblity beingeasierwithmore to paw and knaw vs a drum, might make it last longer. Though restocking timeframe may be shorter. Transporting and clean out no brainer. Have you or the builder tested the theory in the field yet?
Very interesting..thanks.
BTW, Good luck on the blackie's!!
