Pros: easy to use, great quality components, long lasting, work well with braid, last a lifetime, great warranty policy, work great with just about any reel, I have used them with Convectors, Squalls, 330GTI, TLD/TLD2, the Penn 330GTI being my personal favorite but since being discontinued the TLD is my current favorite.
Cons: a little stiff for early season schooly sized fish(14”-22”class) It is tough to even see bites on umbrellas on smaller fish.
