With the hg you're getting a faster gear ratio, just like in baitcasters. For example, a Metanium 100 (6.3:1) vs 100hg (7.4:1) vs 100xG (8.5:1). This has advantages for different situations, personally I would prefer the hg for anything I do with a spinning combo, dropshots, shakeyheads, tubes, etc. Basically the benefits of the c are a 2500 size reel with a 3000 size spool, which does nothing for me. I'd rather have it the other way around.
