I have not had good experience with the blobs, but I know that others have. They have different density targets. I guess it depends on how they get the mix.
Very reasonable, but not mobile.
The 18-1 is a good target and we can ship you a blem so you can save a nice chunk of change.
The block is the worst of the bunch...take this all for what it is worth. Some will say yah, he sells the Rineharts, what else would he say.
I will tell you that I have owned all three and find it hard to sell items you can't say good things about.
