Here's the field use review:
Used the flashbangs (as grenades) and the baseball grenades.
I got a few kills with them, they are (as Delta pointed out) difficult to arm, and I did bring a pair of needle nose pliers to use (Mikey has a technique for loading them by hand... patent pending).
I was able to throw them at least 20yrds, I have girlie arms BUT Greg was able to toss one approximately 35yrd... (Greg correct me if I'm wrong).
Pro's: Its cool that they go 'Bang'
Cons: Break easy (I cracked one off a fence post)
: Difficult to find (Mikey mentioned about painting them orange)
: Sometimes they go off when you pull the pin and kill you right before you are going to throw it into a building killing everybody inside winning the day... but instead it goes pop in your hand and people laugh at you as you leave the field
I would recommend the rubber grenades. I've got a chirp circuit made (for locating the grenade), so once I get some I'll test it out.
