bite does 75 damage,  leap does # of hits x 4 damage.  Is it possible to do over 75 damage in one leap, or is leap mainly meant for closing the space so you can get in a good bite?

leap really does damage but i dont really know how much...it's pretty nice effective still and of course when you get good spot you can click leap several time on same target witch guarantees frag But i am pretty sure that "skill" combo leap and dozens bites will to the trick better...just remember fast fingers and hud_fastswitch 0  

The problem i have will kill with Leep is that i hardly even can land a hit.  I usualy use it to close the gap between me and the RIne so i can bite his ankles off.

Side note i have gotta 3 kills with LEEP thus far, but thats it. Its sooo freaking hard.

Its nice for a quick hit and run. Sneak along kill a marine and then leap away to a vent or somin. Take them slowly one by one  

Run down hallway.
See marine. Hit 3.
Aim, click.
Hit 1 in mid air.
CLICK CLICK CLICK!!!!!

Run away after a nice effecient kill.

I especially like waiting cloaked on a wall above a door, even better, the door to the marine base. Chuckle constantly, and when you see someone, scare the bejesus out of them by leaping down their throat.
