I didn't see you "pick" your desired height. My point is higher isn't always better!
The downside of course, of big risers is accidental contact when moving around the stack which does a whole lot of ugliness in a hurry. Also of course, is that movement should be minimal! and therefore the risk of contact should be minimal. But, in my world of always improving but amateur, I have made risers (of various materials) that were too high and then I was contacting them because my hand movement is not as well controlled as it should be.
Sheet cork is one of my favs...looks and feels good. You can see Matt Storher spend an hour on it, in a quasi-art form of buildup. Or less so with similar results by stacking
Message/bottom line: figure out just how much height you need before hand. Yes, you can trim it down with a razor knife afterwards, but it doesn't look as nice as the "one and done" smoothness if you "measure twice, cut once".
Or, write to your congressman/woman and seek legislation that requires all saxes to be made with height adjustable left hand palm risers, like ________ does.
