Black Francis:
The lines hold up very well. That SA is really like a heavy shooting head with a bit of forward and rear taper to it. If you cut it @ 15 feet it will throw any sinktip matched to the line weight, the heavier lines (8/9 and up) will handle T-14 with no problems. What I did was cut the line @ 15 feet, weighed that, and matched that with tips of the same weight. For example the 15' floatig tip I cut off the 8/9 weighed about 112 grains so I use an Airflo 15' type 8 tip that weighs 109 grains. Works very nice.

I just recently got another 8/9 Delta floater ( after cutting the original, wanted another one uncut as they are so nice) and it had the bump in the running line at the junction where it meets the holding line. None of my other Delta's have this, whether recently purchased or older lines. I know it was a new production line since I spoke with the fellow who sold it to me and he had to order it from Rajeff since he was out of stock. I have heard stories of others who've experienced some lines with and some without that bump in batches of lines coming in at the same time. I'm not sure if it's not just an anomaly in the production process. Mine looks like the core is 2 pieces laid side by side and coated over with the line coating.
For marking the Delta lines a single mark somewhere in the rear taper is all that is necessary. You can judge the sweet spot by moving that mark just inside or outside the rod tip. ( I know that you know this, just throwing in an FYI for anyone else trying this) These lines cast poorly with more than a foot or so of overhang. I liked the plastic tubing Rajeff put out to slide up the running line that would mark the back of the head as it butts against it, but with the "Bump" in the line that won't work.
