Sklansky's Books in relation to Table limits.

[tyboy74]

Since most of the people who read these posts on 2+2 have read at least one of David's book and play poker. If you understand and know how to apply most if not everything that David have taught in his books (TOP, NLHTP,HPFAP etc) what table limit should you expect to make a profit in?? 5/10? 10/20? 20/40? 40/80??? Any comment or advice will be most helpful.
