I think it depends on what qualities you may want to tame or control. (I’ve been a Vic Firth artist for 6 or 7 years now, so most of experience is with their models.)
If you want to get a bit less wash, you could try something with a long taper - Erskine Big Band, any of the Firth American Jazz series (I like the AJ3 and AJ4), or even a Regal Tip Jazz nylon. I also use the Firth MJC5 to tame a bit of wash and add some bite to the stick attack.
However, if the goal is to mellow out an overly metallic stick sound (which is what I might be hearing a bit of in the sound file) a maple stick and/or arrowhead or small ball tip can help. Try the Firth SD11 Slammer (perhaps the most misleading name for a stick!), SD4, or the first Peter Erskine stick (PE1). The Firth MJC2 has a combination of a long taper and an arrowhead tip, and will simultaneously control wash and give you a darker stick attack. The aforementioned SD11 Slammer is very similar in design, but larger.
Hope this helps!
Thanks! There is a bit of a metallic stick sound which is probably amplified in my small basement space. The SD11 Slammer might be perfect based on the length and diameter with an arrowhead tip. I'll pick up a pair.
