The killcam mod... what % do you set killcams on?

I was playing on 100% for awhile but wondering if I am hurting the experience some... they don't always trigger, and I don't mind being vurnerable during them (kind of like that actually)... but do people get sick of them (when playing a melee character)? I never get tired of ranged box kill cams... wish I could set that to 100%

I've played with TDoD for a long, long time and I enjoy most of the killmoves in the game, makes it seem like my character can do more than just swing his sword left & right. I used to play on 100%, but lately I've dropped the settings down to 40% and found it more to my liking as it can get tedious when you see the same two killmoves while spelunking in Nordic ruins.. I always play without the last-enemy requirment though, so I still get them fairly often.
