I would not worry about being good enough... if playing dbl bass patterns is something you want to get better at then just working on it will put you farther ahead than not. Really, all you need is to get a few quads, ruffs and 16th note/1/8th note trip grooves happening and you have justified the endeavor- it shouldn't take you long to do these things, especially since you understand the subdivisions being a drummer for as long as you have.
Musicality is subjective. If the people you play with enjoy your efforts and you do as well, then there is no problem.
You won't suck, no such thing, remember? YOU ARE A MASTER MUSICIAN!
I just started playing traditional grip this year. No big deal, it's something I wanted to do. Same with hand percussion, same with piano (my limitations don't stop me from making my music).
NEVER SURRENDER and then one day you just might win a battle or two. It's the journey, not the destination.
WHOA! Its like the force is with me and stuff

Seriously, thanks Felix-those are true words of wisdom. We, as musicians will never know enough-we are constantly learning. And it keeps us from being bored. I havnt sprung my new endeavor on my bandmates yet. Im not sure if I will-Ill just keep playing my standard setup, as I know it would freak 'em out bigtime

Hmmm.....then again, I can get a BIG hair wig (circa 1982) and suggest we try covering some Poison songs? Naw!!!!!!
