Um, I wouldn't. Unless they take all the mistakes out. I noticed several when I was going through them (I don't just mean errors of reasoning but actual spelling errors and the such). I think all the basics are pretty much in there. I doubt they will have a new technique that will help anything. Have you tried looking at other sources like SuperPrep maybe if you are still having trouble? I think the best thing about the LG Bible is teaching you setups, from there, it's just execution. It's hard to improve on that but that's just my two cents.
