Sounds like an interesting proposal, I don't know of any strain that needs a 6 inch screen hole for each top, you may end up with a lot of open canopy.
1-2 inch holes are really ideal, at least in my experience. The smaller the hole in your screen is, the easier it is to manipulate the direction the branch is growing, alot of scroggers use 4 inch, that works great as well but bigger than that and the branch kinda gets to do what it wants, it can be hard to get an even canopy when it takes 2 weeks for a branch to go under one hole and up into the next.
I must admit, I haven't read the book you speak of. There are so many marijuana horticulture guides out there and so many of them use dated information, at this point I get more "bad info" from published works than from forums like this. Another grower friend of mine swears by one book they got when they first got started and over the time I have known them they have progressed very little, using basic info, a good portion of it incorrect IE; "taking clippings from a budding plant is fine and will not effect potency". This is published information that is just not true. I would be very wary of any paper-copy books on marijuana horticulture, anyone can write them and publishers will produce them because there is a market for it, nobody really checks the information before it land on shelves.
This is all just my opinion. Like I said, I have not read the book you speak of but I have read many books over the years and learned one thing; Marijuana is a weed, ideal conditions for growing are the same as really any other plant and everyone does it different, some people run 6.8 ph and flower with 10 hrs of light, this isn't wrong per-say, the plant will grow under these conditions, the other truth is that many people that have grown marijuana for years don't know what potency truly is. I have spoken to people that grew buds with maybe 10% thc and thought it was "the best thing the ever had". There are still growers out there that think more "hairs" mean more potency.
In the end I would say take every bit of advice with a grain of salt, what works for one may not work for another.
I got into a bit of a rant there, most of that was not focused at your question, more at growers in general. Be happy with what you grow, don't tell others what you do is "better" because to them it may not be.
EDIT:
After I posted this i went to read some excerpts from the book... I am an adult and can admit when I am wrong and in this case I am. West Coast Masters are very knowledgeable growers that have compiled an excellent reference material for medical growers. I will be purchasing they're book and when I am done reading it in full I am sure I will be recommending it.
