Your chosen Controller sensitivity?
An odd question I know, but its a conversation that, oddly enough pops up rather often on XBOX Live, sometimes ending up in players bickering over whats best.
A high sensitivity has its advantages, like being able to whip round in any direction behind you and the ability to "snap" very quickly to anything in front of you. most of the good Halo 2 players use anything between 7-10 (and for 360 users out there, have "high" set as default).
On the other side of the coin for alot of people (especially those new to the controller) a high sensitivity can take a bit of getting used to or even makes aiming impossible entirely.
A lower/medium ranged sensitivity offers more precision and makes aiming easier overall at the sacrifice of aiming/turning speed, but some people will tell you (including myself) that this isn't true at all, in fact I play with both high and mid-range (depending on how my thumbs are feeling that day) and I am more confident and get more headshots with a higher sensitivity.
I was just interested to see what people choose and why, because at the moment it seems more people use a higher sensitivity, even people prefer lower settings are "training" themselves to use high. (ie. Notching it up a little bit at a time, or just plain getting used to high)
