I have rear drag spirex reels (1000, 2000, 4000). It is easy to set the drag
without getting you hands in the way of the line. There is also a quick setting
macro adjustment to the drag.
The spirex also has a trigger system. This is good if you are fishing in cold
weather and want to wear gloves.
Front drag is more popular on account of it's durability.
I use my spirex for bass, pike, salmon and carp. The macro drag adjustment is
very good for carp and salmon which make explosive runs on hookset.
