Quick question regarding #1. Did you initially learn trad grip only? Or have you always played both?
I ask because I am pretty much exactly the opposite.Everything comes easily in trad grip, and requires effort in matched.
I’m sorry, I missed your question back when you posted it. To give a late answer…
Yes, I initially learned trad only. I learned on orchestral snare. Matched was a timpani grip.
For years I was a grip snob, & looked down my nose at people who played matched. Then I got a kit, and realised matched made some things easier, so I switched and played mostly matched for a few years.
However, when I picked up the sticks again after a 30 year break, I instinctively went with trad. Go figure
