I also wanted to note that a lot of users, I found on the Web claimed Dugi’s Guide to be faster. However, all these users had either used Zygor Guides for very little time or had not used it at all. I have to give a point to each Dugi’s Guide and Zygor Guides as they both deliver a great lvling speed. For all you Dugi’s guide users out there who really feel that Dugi’s Guide is faster, I will give Dugi an extra point. If there really were a difference, it wouldn’t be by much.

This gives you a massive 200-percent bonus to experience gain from most actions (though experience from quests isn’t included). The amount of rested experience you earn increases the longer you’re logged off, and your experience bar will be blue (instead of purple) while you have the bonus.
I used to use his profession guides they really did help in the pre cata days (before WoW professions site was around) It's really up to you he does keeps his guides up to date and he does he homework (I still get emails) Their are some free leveling power leveling add ons to help you level much like the paid guides.

Heirlooms are special pieces of armor that level up with your character, so they have stats that are always respectable for your character’s level (up to level 110). Heirlooms that fit the head, shoulder, chest, legs, and back armor slot offer an experience bonus. The total bonus is 45 percent if you have them all. It’s also possible to acquire a ring that adds another 5 percent, but you must win a fishing contest acquire it, and that can take some time.
