who is Brron Jacobs/limit holdem em specialist

[MicroBob]

He wrote 'How Good is Your Limit Hold-em?' which is a pretty good book imo.

He also has written some other stuff including some of the better articles in CardPlayer

I liked Ed's DVD set very much (thanks scorer) but I'll be interested in Bryon Jacobs' DVD as well even though I expect it could be quite similar.
based on how much I liked his book though I think his DVD should prove beneficial to my game.
