I use VF 5B barrel tip sticks as my main go to ticks, 16" with a medium taper with lacquer finish. I used to use the Steve Gadd signatures at one time but I prefer these now, tiny bit longer.
I bought a pair of Promark Rebound 5b's which feel really good, I like the lacquer on them, seem very fast, keep cool in my hands and feel very solid. Interested in trying out the firegrain series
On a pad I use VF SD1 general which have a round tip, are a bit thicker and 16.38". I find they work my hands a little more which builds my endurance. I don't find the length affects my playing, maybe I should try them on the kit.
Recently I bought a few sets of Maple Stagg SM5B very cheap off ebay and have been very impressed with them, nicely made and feel good in my hands, a nice change at the kit when I put down the VFs. I would certainly use them live.
Might try out the Bill Bruford signature stick... just because I am still 12 and a big fan....
