I'd love to see a chart showing the weight, cost, and heal rate of: Meat
vs Meat w/ Poodle
vs Meat w/ SprRabbit
vs Mastelas
vs Cake
vs WhiteSlim. Cakes aren't really a plausible option (in my opinion) but finally knowing the best option would be great!
I can say from personal experience that with mastelas you can find yourself frantically spamming your hotkey when you've got an oversized mob. I'd imagine that that situation occurs more when using meat w/poodle. Then again, I rarely ever knew when to stop mobbing big. Sometimes you just gotta fly wing away.

As far as replacing Hellpoodle:
Mimic card is good if you've got great luck with OBBs. I personally don't though.
The plasma card is also neat to filling in the slot. It'll drop an elemental pot or two every mob (sometimes about 4 a mob. @_@.)
Greatest General card can give you more ATK with hyper spirit spheres. (.02% chance per attack though. Bapho may make it proc incredibly fast)
Owl Duke for Impostio Manus lvl3
Hydro card does cast cancel at 10% per attack and you can try it out mine if you'd like. (this is verrryyy useful with a fast ASPD character and it can stop alot of those decrease agilitys, Dullahan's crit, etc.)
You can also try out my Raydric Archer card which makes demons drop a box of resentment every 1/100 or 1/200 kills.

(box of resentment gives 20 atk for 60 seconds. It's hardly worth it.)
I heard somewhere that blazer's effect can't be stacked.

Good luck mobbin' Nestro!
