I just got some Iron Cobra pedals last week, but I didn't get the beaters because they weren't included and I thought i could just use my old ones. My old wons are really clunky and old and heavy on the pedals and I'm pretty sure it's slowing down my playing.
So, for all you drummers out there, which beaters should I get for my Iron Cobras? The options are wood, rubber, or felt.
These are them:

I'm playing on a regular bass drum head, I'm not playing on a practice kit with a rubber pad or something. If that helps.
