You decide whether or not to add  to your mana pool as the delayed triggered ability resolves at the beginning of your next main phase. You don't decide before then.
10/1/2007
You can't add just some of the mana to your mana pool. You either add all the  to your mana pool or none of it. All the mana you get this way is colorless.
