[Arms]Gurthalak Vs Experimental Specimen

[dragaunus]

i get "Gurthalak, Voice of the Deeps" at LFR and i have normal Experimental Specimen Slicer.
I did a test of 5 minut on Dummy 85+ with both and had the following results:

LFR Gurthalak :: 23.060dps (9% tentacle)
Normal Experimental :: 23.489dps

with this results is recomended use Gurthalak to try my luck with procs? regardless of your stats are below of the Experimental Specimen.

Ps: Forgive my english...

The mindflay benefits from spell debuffs on target, try them both in a raid setting.

when it´s only LFR version, then I would go for the axe.
since you get alot more stats and weapon damage.
you could swap weapon on Yor'sahj the Unsleeping when bladestorming on adds etc for a huge amount of tentacle procs :P the same goes for madness with bloods ;) it´s a sure benefit with bladestorm.. but at any other time i would go for the axe.
