Practice helps. This one is tighter. Now I'm learning how to see the flaws too. Dang!
I liked a couple things about Toss's directions compared with Samson. Toss has you pull a couple cover marker lines at key locations. They are used as landmarks in the splice. They are also used to secure your work via sewing. Sewing the crossover point not only secures it from moving, but it assures that the crossover is less bulky when doing the final and more difficult tuck. That helped me get a full bury of the cover.
The snare on the splicing wand is very cool and makes the tuck operation a "pull" rather than a "push". That it easier. However... when setting up to bury the cover in the core, I found that the Samson fid didn't have a tendency to snag core strands. I snagged core strands twice with the splicing wand and had to start over. As in everything else, practice, practice, practice.
The Toss directions were a bit hard for me to follow. The next time will be better. One thing's for sure, I'm only good for about one splice a day so far. No chance I'll put any riggers out of business any time soon!
