Like several others I suggest going with the BBSII rather than the I. I use several II-III for 3-5 weight rods, usually shorter rods where the Battenkill Mid-Arbor (now 1% different and called the Access) doesn't balance as well. If you went with the I, you could realistically only use half a DT line with maybe 20 yards of backing.

In regards to failures, the reel I had fail the most ever was a Ross Rhythm, and that was also one of the most expensive reels I've ever owned.
