I've read the guide, Rage. I like it. One thing though. The Jetbikes getting T5 is wrong. The +1T is only applied once, whether mentioned in the FAQ, Codex, BRB, or a combo of the three.
I see why you think that but can you prove thats the defualt way? This didnt used to exisit until the new FAQ and there is no reason the toughness buff doesnt stack. As far as i know only the Eldar currently benifet from this loophole but chaos can mimic it with MON bikers. Please cite realavent page#'s as to why it doesnt stack.
Edit: You have to understand the way the FAQ is written there is actually a order of operations as to what you get by equipping a bike.
In the following order this is what you get
"Twin-Linked Shuriken Catapults...The riders toughness increases by 1..it also confers a 3+ armor save..AND FINALLY it changes the unit type to Eldar Jetbike.
Since the verbage "finally" is in the faq any + or - is applied last.
When we visit the BRB to see what a Eldar Jetbike gets the very first sentence in the rules tells us that a Eldar Jetbike follows all of the normal rules for bikes and jetbikes. It then tells us we get the assualt move.
When you go read the rules for bikes and jetbikes the very first rule is Armored Steed which increases the riders toughness by 1. The second sentence is very important as it then tells us any unit which already has a bike as part of its standard wargear already has the increased toughness as part of its statline. Since a Autarch/Warlock/Farseer does not get a Jetbike as standard you would apply everything as it is written or in otherwords RAW.
The Eldar FAQ is the only one that amends a bikes description all other codexs say the bike/jetbike simply changes your unit typs in addition to changing what weapon you have +misc rules.
