What I'm looking at is a team consisting of Primeape and Manectric will run through you. I don't much like the thought of Mantine in a metagame full of bolt beamers, so perhaps just go with the old fashioned Grumpig/Hypno.
I agree with Aquilae, Kabutops is only a hinderance, really. I must say that one of my current faves in UU is Kingler.

Jolly
252 Atk, 188 Spd, 16 HP, 52 Def
Hyper Cutter
Rock Slide
Crabhammer
X-Scissor
Brick Break / Return
I use this as a lead. I've changed the Smogon set to allow it to beat Jolly Swellow by 1 point. (Tapping out at 256, which equals 384 with choice scarf)
You may like the Choice Band variety better, but overall it is better than Kabutops. 115 Def is nothing to sneeze at, it should be able to survive 1 on 1 with another Physical Attacker that doesn't score a SE or Critical hit.
