I use the tubajedimr questing profile 1-68 (until 60), then I use the 58-68 outlands quest because the previous quest profile gets stuck at the quest where you have to find keys in the felhound shit, after that it runs flawlessly until about 68, sometimes 69. Once I hit 69, I use kick's grinding profile in howling fjord until 70, then I train herbing or mining to 400 (and flying 280%) and stick my toon in sholozar basin to harvest herbs or saronite until 80, then I begin farming herbs in hyjal or obsidium in hyjal until 85.
58-68 quest profile is pretty afkable, the 1-60 I use isnt as afkable but requires a few fixes or nudges every 5-10 levels..
I use paladins, protectin paladins level pretty nicely, I switch to ret when I grind 68-70 then back to protection so they can tank the 3 level 76 mobs occasionally happen while harvesting in sholozar, I change back to ret at 85. I also use mritemremover plugin to delete saronite or herbs so my toon doesnt have to deposit or mail anything, and frankly I dont want to waste time listing that shit.
I use profession buddy to get gathering to about 200 but by then it keeps getting stuck in barrens on those green tentacles that dont attack you but put you in combat (forcing bot to sit around saying in combat but no target) so then I do felwood to 230, then ungoro to 300 and hellfire to 350, then borean to 400 then onto sholozar. I edited the professionbuddy ground profiles to work for herb or mining separately. I dont buy cataclysm until I need it, I havent gotten any suspensions or such doing it this way.
The lowhanging fruit questing is nice but the tubajedimr will do 1-10 for me

, but after 10 I would use either (I've switched between both when one would have errors I'd go to the other until it had errors and then back to the original etc..) but lately I've worked lot of the kinks by deleting some code in the tubajedimr so it runs smoother.
Only PITA is that when I make taurens for herb farmers, they get stuck on everything, specially with how HB tries to cut sharp corners. I've used this method on my last four paladins, before that I made DKs that I hand quested out of the dk starting area, grinded to 60 then would hellfire gather farm, but this is way faster

Before all this, I would just use grinding profiles but now we all get suspensions from that. I actually like my paladins over DKs because they can heal and last longer against higher mobs/groups. blood DK can do sholozar gathering at 70 but will die more than a level 70 protection paladin..
It might seem a little slow from 70-72, but once it hits 72/73 it really picks up pace and hauls ass. If there was a reliable questing profile 68-73 I would use it but there isnt really, so to avoid more babysitting after I hit 70, I just let him do his thing in sholozar and go about my way (24/7) until he hits 80, for new flying and onto hyjal.
If lowhangingfruit has no errors though, I would do tuba to 10 then lowhanging to 60..
