I have some experience with inline spinners, the inlines are a pretty good bet! If you play with different versions..... small to large blades will track well wether burning or slow rolling them. you have to take the fishing conditions into account ( current, depth, type of fish, and so on ) one thing is for sure inline spinners can be fished fast or slow. I have problems trying to slow down a spinner with a clevis and then trying to start the blade again, with the inline spinner you can bring it almost to a crawl before the blade stops and restarts very easy. btw the pm 6 size I believe is a #4 blade if you going to make it exactly the same.
