Recently I have  throwing my spro bronze eye frog to the weeds and open areas and am noticing that my frog is on it's back!  I need the white belly down..any suggestions?

Well lets see here, first off do you squeeze the water out after every couple of casts? If not that may be your problem. Secondly make sure the lead weight that's "molded/positioned" into the back of the frog is still in it's correct position. If you've added any additional rattles make sure they're still able to move freely inside the body. After this I'm pretty much out???

I've never had this issue with quality hollow bodied frogs, spro included.

I would be guessing you weight is gone.

I second this. The counter weight could have fallen out

Also have never had a problem with my Spro frogs floating belly up.

I haven't had a problem with them yet ethier, did you figure out the problem yet?
