So far the boomers seem like a nice middle ground but I'm waiting to see how they age after reading all the posts here about them dying very quickly.
One's "dead" is another's "well-broken-in". People who complain about the Boomers "dying too quickly" are usually the ones who feed on the zing of fresh rounds.
There is a reason why they're called "Boomers" and not "Zingers".
