What is the fastest attacking skill in the game?

I'm currently playing a monk and Bell is such an incredibly powerful skill that I started to ponder how to maximize its potential.

My thoughts so far:

I could run multiple copies of the Bell, possibly with Overabundance to double them again (reduced duration shouldn't be a problem), and use Gemling for more skills slots (more Bells), and the possibility of using the same supports.

But the question is what to use as the main skill.

Combo buildup requires melee but the Bell can be triggered by anything that hits, so bows/xbows would also work, although they would require a weapon swap.
A melee skill would be preferable for the easy combo+trigger setup by a single skill.

EDIT: I wonder if Flicker Strike would be able to target the Bells. From the tooltip of level 16 gem, it has 275% more attack speed and teleports 2x per power charge. And from the clip in the skill overview, it looks like it can hit the same enemy multiple times.
That makes me wonder if Flicker Strike with Charged Staff active does send the waves with each teleport. Waves could be enough to trigger the Bells.
