I have reels with drags ranging from 20+ lbs. to 8. I typically don't fish a lot of heavy slop, so drag power, for me, really isn't that big of a deal. In my opinion, 8 to 10 lbs of drag pressure is plenty. In fact, I tend to adjust my drag pressure down a little and may bump it up some if I get into a good one and feel the need to slow it down just a tad.
Also, I should point out that I typically use 10 lb test.
