It's a sad time, but FYI OSAGE ROOST will be pulling the plug at the end of the month. It's been a great 15 years since the start, but it's hardly ever used now and time to move on!
For what it's worth, I do tune my strikers. I have a basic design. Once I get close, I start running them on all of my pots and sanding, shortening, thinning it until I get the sound I like. I shoot for a balance among all surfaces, but I have a sound that I am looking for. Once achieved, I stop and finish the striker.
