Interesting Rob, I hadn't come across the blob knot before, always use an Albright with the braid doubled. Had a look at your link and, if I read correctly, it says the blob knot is only for mono lines. Clearly the leader blob needs to be mono, but have you used this ok with a braid running line?

No, waiting for you to try it first!

It would work if you used a 10 turn Grinner on the braid around the mono. and then slide the knot down to the blob just before fully tightening.

Sounds like an at home test is in order!
60lb mono to 30lb braid and PULLLLLLLLLLLL!
Hmm, we use 80lb leaders and a J knot and have no probs with knots going through rings.
Not sure what the problem is ....

We've been using the J knot, as described on the webknots page, for past few years and only had failures when using light (under 30lb) leaders to 20lb braid. For the usual 30lb braid to 60+ leader it just works and is a neat knot.
Hope this helps
