Immaflipper

So, I finally got internet back 2 weeks ago or so allowing me to blow through the last 15 ranks or so in COD4.  When I first got the game I intended to stop at 55 and be content there.  I didn't want to raise peoples expectations when they saw a prestige, low expectations are good, ask my wife.

For some reason I got the bug, like so many others, to flip to prestige and start over.  I don't know why I got the sudden urge, but as soon as I could, I flipped it the other night.  It's really not that bad.  I'm ranking up much more quickly this time, I think I'm back up to 18 or so.  Not only that but I'm going back to the basics again and not relying on my 3x frags quite so much.  I was considering going to therapy for my grenade spamming problem, this effectively postpones it for a bit.

I never really used the dead silence perks, bomb squad or some of those others that are unlocked at the higher levels so I don't feel like I'm missing a whole lot.  I'm hoping to use some of the other weapons this time through.  I've never touched a shotgun or the mini-uzi or most of the snipers.

Now the question becomes this: Do I stop at 55 this time and try to complete all the challenges or have I gone down a slippery slope that I will never be able to stop?

Another question while I have you on the line....what is your head shot percentage?  I think mine is only around 10%-12% of my overall kills, so the achievements take forever for those.
