What you refer to is the Tuscan Levelling System (with the straps/zip gun) and it is the real deal. It is also rather pricey to buy and use once...
Of the two "clip systems", Ramondi's is far superior to the mass-marketed "QEP" one that Homer D Poe sells.
A note or two about using these:
They are
not a replacement for adequate subfloor preparation. With large fomat tile on a rollercoaster subfloor you will still have "issues" they will just be "different" issues. Adequate mortar coverage will be the biggest of these in most cases, leaving hollow "voids" in low spots where the tile will not adhere properly to the substrate. It may look pretty for a while, but the bond will eventually fail and cement based grout will crack and fall out.
The best piece of advice I can give is: PULL A STRING ACROSS THE SUB FLOOR AND ASSESS HOW FLAT IT IS, PRIOR TO DOING ANYTHING ELSE.
If it needs to be levelled?
Buy Self-Leveling Compound and pour to fill the voids you find.
On a perfectly flat floor with consistently gauged, rectified porcelain tile you should be able to set 24x24 on a brick pattern with no issues what so ever.
Assessing what is "good enough" for flatness depends on what you're trying to achieve (pattern), the consistency of the tile you're working with, and your ability to "work" your combed mortarbed to keep things where you want them.
A level subfloor also assures that you are not "chasing" your groutlines; these are
very much affected by even minimal changes in level/azimuth.
Always backbutter your tile and buy high quality mortar that has not passed its "best-before" date...YES, it has a shelf life.
Anyone in the Edmonton area who wants help/advice with this kind of thing, feel free to PM me. I have accounts to purchase setting materials, Schluter system items, proper tools etc, wholesale; directly from the same place that Homer buys them. Lets just say that I can save you many, many dollars (i.e. 40>60%) versus you buying at the box store. The markup on most of the stuff is crazy.
I've been setting tile since the mid-90's and primarily build high-end custom showers these days.
