Table Selection Strategy for 6 max NL

Hello , I have recently started 1 tabling NL600 and lost $2,500 to a combination of variance and tilt. This has got me thinking.

I've searched this forum thoroughly to not find much discussion about table selection. Clearly this is extremely crucial to determining success. Ever since I have started 1 tabling 6 max, Poker Tracker has tagged me as a SLAA(semi-loose aggressive/aggressive). I have found it necessary to run Poker Tracker on the top avg $ tables for half an hour to an hour and then get in line on the best looking tables and see which seats are available to me and if these are good circumstances for playing. I go by the guideline of, not more then 2 short stacks allowed, no good LAGs to my left, and generally players which have some obvious flaw in their play.
However, it is absolutely unclear to me which approach is the most optimal for improving your skills and meanwhile earning a nice hourly rate. There are clearly very diverse styles in this game, but I find that the passive players which are more capable of letting go of blinds but aren' that are easiest to play against and more profitable for my style because long-ball bluffs also tend to be more succesful against them. Aggressive players I find put you in far more difficult situations where I end up tilting sometimes, even with 1 table, even with the fact that I review as many hands as I can that i have from data mining in Poker Tracker for each individual player at the table. I was even considering a strategy of finding an incredibly passive table which gives up blinds a lot and playing a good selective LAG strategy to steal many blinds, while still being capable of tightening up if table image grows to that of a maniac.

I believe this is a great discussion for everyone to add their knowledge oh what is the proper way to approach table selection online. What criteria for table selection have I missed from the written above? What kind of table composition is most profitable for 1 tabling, or even multi-tabling.

I personally find that with all of the incredible hand reading and adapting to each individual that I have to do for 1 tabling that it is pretty much impossible to do the same 2 tabling without getting less information about each player individually. What is the optimal amount of tables strategy? Also, would a strategy such as perhaps buying in for half max buy in in 3 passive tables that give up the blinds and just stealing as many blinds as you can while avoiding difficult decisions, be more optimal then 1 tabling and still having to often face very difficult decisions for your whole stack ?

The skill of table selection and very in-depth dynamic hand reading is perhaps what seperates the amateur players from the professionals. This may be a great opportunity for everyone to learn something incredible for their skills.
