Which way should I recycle my yeast in this case?

I am using a yeast that I planned on using on one batch, then another. I'm about done with the first batch, but I thought I'd stretch out the yeast into a third batch as well. I only have enough equipment/room to do one at a time. This is a White Labs yeast. Now, would it be better to:

A) Recycle the yeast from the first, use it into the second, then recycle the yeast from the second, use it in the third batch.

OR

B) Recycle the yeast, but split into two containers. Use one right away for the second batch, but store one in the fridge for two weeks until I make the third batch.

Basically, it comes down to which is a greater infection/yeast-death risk... using some that's been in the fridge for two weeks or using some that's been through 2 week in the fermenter.

Cyanide I think you would be better off just using it from batch to batch. The only thing there is that you kind of need to go in some type of order. (ie; light to dark and less hopped to hoppy) This will help if you are just putting your wort over into the same fermenter. If your gonna harvest the yeast then it would not matter very much as long as you took care and were sanitary.

Lightest to darkest is a good way but I would not worry about the hoppiness of the beer. Actually the hops being aseptic are a better way to go. When we make starters or are propping in the brewery I either use the hoppiest thing I have going or I make a fresh starter and crank the IBU's up.

Go from batch to batch unless you are harvesting enough from batch #1 and then brewing #'s 2&3 within a few days of each other.

What about if my first one was kinda dark, but I want the second to be light, in fact, a cream ale? Normally, I would have done the cream ale first, but I didn't think about it until after the first batch.

Should I not even bother? Or anything I can do to keep the flavors of the slightly dark one away from it? The first one was an oatmeal stout, but a very light one.

you could try washing the yeast...
