I've got a piece of clear plastic that I put my products on while shooting, and I get a slight reflection. I believe if you put your product on a shiny white plastic piece you'll be able to get the reflection.

You can take your 1st strobe with the softbox and use it to light your plastic piece. Take the second one (you could probably get away with just the reflector on) and aim it towards the background.

Using your camera (my method) or flash meter, meter the flash aimed towards the background until its all nice & white, but your product piece is nice & dark with no light spilling on it. Then you can turn on the other strobe, and adjust the power until your product looks good.

I'll try to get a photo of my product photography setup while I'm at work today & post it.
