Raw sharks are about 900 each, while cooked are slighty less - usually around 800 each. You'll burn a few at 80 cooking. Not sure how many per load though.
Whip is only expensive because we made it expensive, so you can't really categorize items by their price and compare them. Whip has a bad special to balance out it's amazing attack bonuses, just like how it doesn't have a strength training option. I honestly don't see the point of this thread. It's quite useful in Castle Wars and other situations.
Well that's nice to know, but the purpose of this forum is for asking questions and for advice. Not so much posting advice for others. That belongs more in Player Made Guides (if you're a guidemaker) or in General P2P for discussion.
Maples won't ever be as fast as willows, though they are relatively fast at that point. Not sure about your second question. Cutting 11k maples would be quite helpful for your WC level as well as saving money, so I'd say go for it. Yew Longs are around 500-550 each. You'll lose money if you buy the natures, but if you craft them then you won't.
I'm not too sure of their hit but it's good experience, expecially when used at Pest Control. The guy before probablly assumed you would be buying Chinchompas which can be from 600-750 each (prices vary, not sure if these are correct). Hunting doesn't take that long to level. No estimates from me though :XD: .
Yes they're explosive (AoE). When thrown, they'll explode and hit monsters in a 3x3 area. I've heard that with 4 traps, you'll get around 200 per hour.
I don't think he was intentionally telling you "false information". It's true that you need RFD to get through the hole in the basement, and there's technically no other way to get into the cave under Lumbridge Castle besides that hole (I don't mean the swamp dungeon).
The range there only effects low level fish lower than lobster (or something like that). Forgot who mentioned this but it seems quite true. It hasn't ever helped me with my fish (lobsters/monkfish).
Yes they are tradeable and can be sold. There is really not much demand for purple sweets anymore, and probablly the price is still around 1k each or less. That's what I first bought all 700 of mine for when they came out, though now since it's been months since they were out, price probablly has dropped. They can be eaten to restore 1-3 HP and 10% run energy. They're very useful since they're stackable as well.
Yes that's true but a reply is better than none. Also, he did state level 80 so I would think one would catch more, so the last estimate was relatively close.
I would get a scimitar or long sword of whatever is the best you can wield, like Rune Scimitar. Daggers aren't really good weapons. The Dragon Dagger is the only exception because it has a special.
