I switched to Sufix 832 Lo-Vis Green late last year.
First I used the 30 lb which is what I have used on all the manufactures in the past, then went to the 20 lb around 5 weeks ago.
Have had a few wind knots or loops, but the majority of them I have been able to pull out. Really like it, casts great, strong.
When I change leaders I do cut off 1-2 feet of the braid. Never did this with the 30 lb lines, must do with the 20 lb.

This site reviews lines: Paulus Just Fishing (great place for info on lines)

The 20 lb line tests at 41 lbs, Their review of this braid mentions a lumpyness, I have not noticed that with the 20 lb line. Feels smooth, cast very well, very little resistance in the water.
