Derick,
They look solid the workmanship is clearly there and I don't know what they sounded like before you reworked them, but it sounds to my ears that you might be leaning on the striker just a tad heavy for a slate call. I could be totally wrong and forgive me if I am, but I like the roll-over, it sounds strong, but it has a little squeak to it at times and I was juist wondering if you eased off a bit on the striker pressure how that would work. For a slate, and they usually do, it has a great cluck and purr!!
On a scale of 1-10, I would give the sound a 7.0. It sounds good, but I know you can make them sound better! If ya have time post a sound file of a couple other wood combos, they could be quite different.
