From reading the other replies, I became convinced I don't know the real difference between WF and DT lines. I THOUGHT WF meant there was no front taper (all the belly in the first half or so feet of line, followed by a taper to a long running section) and DT meant tapered at both ends, with a long belly in the middle, but people who know more than me and are likely better casters seem to be suggesting there is little or no difference between the two at short to medium distances. I did a little research, and I found a good article at a site where I've found lots of good casting tips:IMHO Cortland 444 is a great line. I have used them for years. Cortland 444 Classic Peach DT should be added to your list.
I'm aware that they are WF, I may end up going that route as it doesn't matter which you use unless you're fishing with more than 30-40' of line which I almost never will be.It is hard to say which grain weight is the best. A lower grain weight is better for some casters while the higher grain weight is better for others. It really depends on your casting style. More experienced casters can adjust to different rods and lines quickly (I am not one of them...).
All the lines you named most recently are WF and not DT.
