Default tentacles

Im looking for best way to animate a poly/subd tentacle wich has to be easy to position but still able to spiral at the end to grab things

tested spline iks but still not useful (or i wasnt able to make the setup correctly) i got it EITHER to be easy to animate OR able to grab, but not BOTH.

(huuum how do you say that it can be done switching between fK and IK?)
and
(can i have two skeleton sets and switch between them as needed?(i mean the active one driving the passive one, then switch...)

Any ideas on how to setup setup such a tentacle?

There's a tutorial here on animating a tentacle which might help;

I don't think you're going to find a one-button solution for something like this.

yep, i diddnt expected it either...

Just waiting to see what approach the "pros" would take to make a tentacle rig with
1 fine control (spiraling at the end)
2 easy general positioning
and
3 extensible/retractible (adjustable skeleton lenght)

to see if i can incorporate any idea to my own rig

I'm just starting a tentacle myself. I'm not sure if I'm going to keep my current rig, but what I did was used Spline IK up to the last few bones, so they would be controlled outside of the spline IK. Then I set up a "set driven key" controller that curled the bones that helped grab objects. Again, I'm not 100% thrilled with the control I have, but it's not bad.
