The information above in post 39 is wrong the DB is a 3 3/4 inch 1/3 ounce or 4 3/4 inch 1/2 ounce plug made for fresh water it is not an SP minnow
The new SP sinking is a 6" long 1.25 ounce true SP minnow available in all the same colors as the SP minnow which is 6" long and 1 1/9 ounces the SP stands for Salt Water Pro. They will be available within the next few weeks a few select shops have them. I have one and it casts a little further and swims a little deeper
