Hi Mike
I liked Minicons as you know. I think they were really designed for lower line-weights. The length was ok by me, never had one fail. I prefer to whip braids on but for a fast fix tube is fine.
I'm interested in the comment about heavier or stiffer braid as an aid for looping on poly leaders - never considered that point.
I've had issues with simple braid loops, where the tucked leg slipped out. That usually happened while I was attaching the loop but once or twice a loop fell apart when I was fishing. I use a drop of glue, usually superglue, to prevent that.
