I like their maple Jazz Cafe sticks for being really light and durable. (I found Vic Firth hickory got chewed by cymbals very quickly.) I bought my last batch years ago. Sad to see they are discontinued.
If someone can recommend an alternative, that will be great.
The Firegrain thing isn't really a gimmick. Using fire to harden wood is actually a real thing. It's mostly used for hardening arrows and spear heads though, and I'm not sure how well it works for drumsticks.
I only use Pro-Marks 5As. They just feel right in my hand. Never had a pair break on me.
