While it's called lo-stretch I imagine it still has a lot more stretch than braid.
Stretch makes working big lures a lot harder, as it soaks up any action you are trying to impart.
Also means when a fish is on, it can actually gain a couple of metres without taking line off the spool, which can be critical. In pump and wind situations it is easier to put line back on the reel with braid - with mono you pull back then as you drop the rod to wind in the mono contracts.
The diameter is a big stumbling block, considering 80lb braid is about the same as 20lb mono. This cuts down both line capacity and casting distance drastically.
Apart from that it's ok though
