Cold stabalization before bottling?

Hey everyone, I have just started using this awesome forum and this is my very first post. Anyway, I am bottling soon and I was wondering about cold stabilization to remove chill haze. I have been having a problem getting my coldbreak to work well in the kitchen sink after brewing but was wondering about doing an icebath in a new tub I bought befor bottling to have the chill haze settle out befor racking into my bottling bucket.
I know that this is done in winemaking, does it also have a place in homebrewing?

If you do it and it works, what temp do you try and get it down to and how long do you keep it at that temp.

THanks

I crash the temperature of my beer to help to clarify and to eliminate as much haze as I can in problem beers. In order to eliminate the chill haze you need to bring the beer down to temperatures lower than your expected serving temperatures before bottling, otherwise you will be stuck with compounds that form at those lower temperatures that did not fall out of solution. As far as an ice bath I see no reason why it wouldn't work in regards to temperature, however the problem I see is time. I usually crash my ales for about four days after fermentation and even that is not enough for some brews. There are actually formula's out there to figure out the rate at which a solute will fall out of solution based on a few variables and parameters...but thats just boring!
