So I assume Pin fix is better because there is no heat involved ? If I was needing this block I would do more with it. But I have 7 blocks here 4 of them test good. so I am going to move on and use other block. I have 3 blocks for sale and does not seem like anyone is interested in them.So I can not see any reason to spend any more money on it. If someone would like to have it. I sell it for what I got in it.
