This is what I wrote -
The profile of - 3. The Mastery Competition, defines it as a line for long casting. This does not mean that if you buy one you will cast further. If you're used to a profile like the Mastery Titan, you'll probably cast less far with the Competition. The Competition is a line for people who can consistently generate and maintain the line speed to hold 70+ feet of line in the air. It is a competition line . . . not much of a fishing line.
I would contend that, for the great majority of anglers, lines with tapers similar to the first two examples I showed, will offer more to them, in day to day fishing terms, than the Mastery Competition or similar lines for the simple casting reason, 'this does not mean that if you buy one you will cast further'. If you can't hold 45ft of line in the air, forming consistent loops then the Competition isn't a fishing line that's going to give you any benefits above any other line.
