river2sea frog are what i use now, they have a little black rubber piece on the hook right at the body that doesn't allow water to get in. I have used both the spro and the tru-tungsten. i find that the tru-tungstens are hard and need to be left out on the dash board of my truck for a couple days to get them to be softer. The small spro frogs did ok for me but when i tied on the bigger ones, thats when i started to get the problem with water. So IMO the river2sea frogs are the way to go.
