Alchemist Explosive Bombs: Can you still pick to throw normal sized bombs?

[Mok]

What I'm wondering about is this line:

"The alchemist’s bombs now have a splash radius of 10 feet rather than 5 feet."

It seems to imply that you no longer have the capacity to throw regular sized 5-foot radius bombs. What if an Alchemist doesn't want to throw a 10-foot radius bomb, has he somehow forgotten to mix the ingredients for a lesser bomb?

It's marked with an asterisk, which means it doesn't stack with other asterisk-marked discoveries. I'd take that to mean that you can *choose* to apply one asterisk-marked effect to your bombs, which would mean that he could easily throw a normal one. Even if it didn't, buy acid bomd or something and you can choose.

The exact text is "only on such discovery can be applied to an individual bomb", which makes it pretty clear that, if you have more than one, you get to choose. I'd definitely allow an alchemist to throw one without any asterisk powers attached, though.
