Hey, congrats on your improvement, thus far!
Firstly, I think you should maybe try to do some of the LR and LG sections timed, so you can get a more accurate estimate where you stand in those sections.
Since you seemed to like the PS logic games bible, maybe you should try to give the PS logical reasoning bible a try. I've heard PS techniques are suppose to be great (hence why I'm enrolled in their full-length course).
As of now, I'm terrible at logical reasoning, but I seem to be doing fine with Logic Games. I think that it comes naturally to me because I have done logic games in crossword/puzzle books that you can find in the supermarket or drug store. If you want to, you could maybe pick them up and try working your way through them. I find that they're harder than the games on the LSAT, especially if you tried to do it timed (I never did, since I just did them leisurely before I knew much about the LSAT). Anyway, after having done them for awhile, when I first approached the Lsat, I found that the LG section came natural for me.
BTW, how are you at the Reading Comprehension section, just out of curiousity?
Anyway, good luck with your studying! Also, as I said, test yourself with a couple preptests timed so you can get a better sense of how well you're doing before you go and buy extra study material. You might not need to improve your techniques anymore, just your familiarity with the test itself and speed while taking it, and would be better off just working your way through LSAT after LSAT.
