With the changes in 3.3 instance boosting still viable?

[blbjtb]

(max range changed from around 310m to 250m)

i boosted my 4 pala toons this way - 3.5 days played without RAF or rested XP

Quests 1-14
Deadmines 14-19
Stockades 19-22
Scarlet Monastery 22-40
Zul'Farrak 40-45
Scholomance 45-55 (best booster ever)
Hellfire Ramparts 55-62
Sethekk Halls 62-65
Utgarde Keep 65-70
AV+Quests 70-80 (quit AV if takes over 10 min)

.

LOL this makes me love you right now =P what kind of toon did you use to do your boosting though?
Edit* Question would it be better to send them to the zones a little bit earlier? like ZF @ 35 instead of 40? does it make a difference? do you get more xp if your more in level range?
