So I've mostly been a skiller/quester in my time playing RS, but I'm working on getting better at combat. I thought I'd pick yall's brains on some things:

What slayer tasks do you all prefer / block and why?

Why do people use rocktails? They're 3 times the price of sharks and don't heal all that much more (300 extra HP at most). I understand for some low kills per trip bosses like araxxor or ROTS it might help, but in GWD or QBD I don't see much difference using them, especially to justify the cost. And then there's rocktail soup which is even more ridiculous for another 200 HP. Am I missing something?

Any other advice/tips/tricks I might not know to help me transition from skiller to killer?

Wooooo killing!

I prefer airut, dark beasts and abyssal demons because they are fast and I enjoy slaying them.

I've blocked black demons, tzharr, desert and lava strykes, skeletal wyverns and grotworms. I just block things that annoy me, there isn't any strategy involved in my blocks.

I use great white sharks for most things. They heal 2100hp and are about 1k gp.

If you use revolution these bars are pretty handy for dps. http://runescape.wikia.com/wiki/Revolution/Bars

Also if you use overloads holy overloads are cheaper per dose than normal overloads so are definitely worth getting.
