Breaking in Putters

[KeithMiller]

I really need to get my putting game on track, so I just purchased 5 new aviar putters, the same weights as my JK pro that I use in my bag. My question- is there any good way to break in putters outside of general wear? Each of these putters is really rigid and I want to get a more flexible feel as quickly as possible with them. What do you suggest?

Go to a park and lay out a "tree course" After hitting 18 trees they should be well broken in. Also, play a whole round somewhere with just your putter.

I personally do not know of a good way to break in putters outside of what Midnightbiker suggested, but I would like to make another suggestion when you play with 5 putters. You also want to make sure that whatever you do to break them in, you do it to all discs evenly.
I am currently playing with 6 different Wizards and the one thing that I am trying to do is make sure they break in at the same rate. I have put a roman numeral on the bottom of each disc so I will be able to rotate all discs for round play. I have also considered putting a dot on the bottom of each disc for each round played for the occasions that I play multiple rounds per trip just to make it more even. I know this is not what you were asking but I thought even break in, would be just as important to you if you are using 5 discs for the same purpose.

I use two aviar (BB, AND REG) for my main putters but would like something for the 50 + foot range putts. Do you think a Challenger would be good for this? The new ESP FLX?
