Pool Tables, Predator Pool School
The Olhausen table is OK, all manufacturers make a Pool table between so-so level to a Great Table, Brunswick included. I have never like Plywood construction, but it is stronger & if cared for, will not cause problems. The type of plywood used is important too, ask questions.
The Pool Tables' playability function is created by good rubber cushions, good cloth & a flat playing surface. That's it. Ivory, Burled Woods, inlaid veneer do nothing for your Pool Game, same goes for Pool Cues. If your economic status is of a nature that allows you to purchase beautiful items for your vanity, I'm jealous. More power to you.
About Pool Schools & local Instructors. The best Professional Golf Instructor (a nobody as far as the media is concerned, but somebody as far as the players are concerned) can not make it on the PGA Tour. Actually he cannot break 80 everyday.... but he can get you to play better than that, if you have the talent (keyword). A Great Player does not make a Great Teacher & sometimes can't even be a good teacher.
I would not suggest a Pool School for the beginning novice. Too much information has to be digested too quickly. Confusion isn't a good recipe for learning. Taking lessons from a Professional that is locally available for you, is there for tweaking your game from time to time & uses Video for your convenience later, is the Instructor of choice. Using Video can be a great way to see what your doing & what the results are.
Buying the Instructional Books or Videos is a GREAT way to learn. Nothing beats knowlege gained. Knowledge gained means you understand the principals & can perform them to a high degree. If you get anybody's book & take it to a pool table for learning & can someday perform what's in it, you'll be a Player & a good one too..
