Re: Reel advice?!?
IMHO, you can't go wrong with either....
The Battenkill seems to have a more dominant usage on this forum-- likely for regional reasons-- If this were a UK forum, the opposite would likely be true.
This being said, you'll probably get many more 'yay's' for the Orvis-- and I'd be happy with following those 'yays'.
Both have disc drags (I think), Capacities are hard to gauge as System 2 has all those models-- I assume you are talking the smaller 78? If so the SA has slightly more capacity for backing/ line.
All in all: a wash-- either are dang fine reels.
