I have at least one pair of all of the above, and I like them all for different things. The 7A's are whippy, fast, and light, but lack punch and power compared to the 2B's, for example.

I'm using promarks and vic firths right now for funk and hiphop i always use 7a's for punk,rock,metal, hardcore and anything generally heavy I use 5bs or 5as. it kinda hurts my hands to go to and from sizes but 7a's just won't hold up. I'm tryingg to get down to using 7as and 5as exclusivley. I'm not sure which brand i like, they both have htier perks.

All of the above, and more.  I like variety.

The 7A drumsticks I have are possessing of a long taper.

440 promarks @$%# near marching sticks im an extremly heavy hitter

Most of my gigs permit me use 5AN or 5BN.  Nothing larger.

Maybe the occassion Jazz sized sticks.

I use 1A  or 5Al which are both similar to 5A but longer in length. Great for my short arms. I like the balance point and power i can get with these without going to 2B.

I always use hickory, nylon tipped.

Is there a point to the poll,. i.e most used stick, whatever?

Until very recently, I used Pro Mark 5b wood tips.  I liked the weight in my hands, and my grip was very comfortable.  I dug the taper to the tip, and the beefy tip as well.  But, as I get older (44 later this month), I feel the physical toll of the weight of those sticks.  I began to get tired after an hr. of practice, or a 2 set evening.  And the tips would get dinged every once in awhile, and mess up my coated heads if I didnt retire them.

So off to the drum shop I went, and after going thru a VERY well stocked stick wall, I selected Vic Firth 5A nylon tip sticks that I have been enjoying lately.  They sit in the right spot in my hands, are the same diameter and length, and the nylon tip gives more definition on my ride cymbal.  The area just below the tip is a bit thinner, but I havnt busted a tip yet.  The weight was weird at first, but that could be expected after using the same type and make of lumber for 30 years.  Another added benefit is I seem to be able to play a bit faster due to the lighter weight, but the biggest benefit Ive noticed is more detailed stick work in general.  So I guess change is a good thing.  Oh, I chose Vic Firth because they were out of P.M. 5A nylon tips!!!!!

I use 5B for general playing.  For lighter playing I use a 5A or 7A, usually Vic Firth.  

I played last night in a venue that was a bit drafty and they had the heat cranked up (Cafe Brauer, in Lincoln Park, for those of you familiar with Chicago.)  Anyhoo, the air in the room was very dry and I was having trouble getting a good grip on the sticks.  I ended up using Regal Tips of the sizes stated above because their lacquer finish makes the sticks less likely to slip in my hands.

I really like the pro-mark Neil Peart 30th anniversary sticks. I picked some up just for fun and ended up really, really liking them. Now, I can't put them down!

5As, no-name except for gigging; then I use a pair of Vic Firths. 5Bs for heavier stuff.
