Tim,
I take the tag end of the braid around the braid mainline, and wrap it four turns towards the albright inside of the loop. As this pulls tight it locks the tag end and stop any chance of the albright working loose. The weak spot under your albright could be caused by how you tie it Tim. Keep the wraps as neat and tidy as possible, then wet it before pulling slowly tight. It is a very common problem when tying the albright with two sections of mono. The trick is getting all the wraps to pull down together. Next time we are on the same mark, I will show you. Also worth saying it is easier to get a strong knot with hard compound fluro's than soft ones.
