The only thing better than XP!, Karma and the giving of... Options

[Brazila]

I am a longtime SR GM and am trying to evaluate how my group gives karma out. Currently I do a team reward that all PCs get. This includes categories for survival, success, and threat. Most of the time each one is worth 1-2 pts. I then have individual awards per the suggestions in SR3. These usually end up with each PC getting anywhere from 2-5 of these. I would say for an average run my PCs get about 7 karma. I am considering doing some changes (see below). I was wondering how other groups do karma rewards, or what suggestions other GMs have? Okay here is the list:

1 Go Iron fist stye and I will give it out based on my opinion of what people did and how much they added to the game.
2 I am thinking about making the team rewards(surv. succ threat) a little higher, but in turn making the extra awards harder to get.
3 Spreading the rewards out more (RPing bad-0, Avg-1, good-2, Great-3 or more)
4 Adding a new category "Player nominated." and having every player give a "best Player" vote and awarding that player an extra point, or maybe doing top 2?
5 One example I saw, that came across interesting but cheesy was.....Everytime a player does something that is awesome (big dramatic speech, awesome quote, super risky stunt that works, says hilarious 1 liner, etc.) the players yell out Karma and that PC is rewarded with an extra point at the end of the run. Obviously you have to set a limit on this or it could get crazy. Maybe a total of 3 "Karma!!s" a run at max. Also I know that the idea of screaming out karma, may seem a little to "BINGO!" to everyone, so somethign similar could be worked out.
