naturally, I have to be the one to disagree. Depends on your gains but i would certainly throw them in - thats only going to take out 28 out of the 100 you are getting, plenty left for the next round. And if all you are running is prop and slin - no reason not to use them - dont know if your time constraint is due to testing.

Btw - the reason you normally dont see them at the end is because most people start out withthem and bombs are better not run for a long time.
