Dear it depends on what your playing level is now which makes the difference on what type of stick. Are you begining, been playing a while? First if you have been playing longer than a few months you shoud be playing with a stick with a little wieght but but not too light. 7A is a very light stick, too light in my opinion, and you will only be wasting energy playing harder with such a light stick. There is no correct or incorrect stick size, its about whats comfortable for you. Differrent sticks will suffice different styles and times, a 7A maybe handy for playing a light ballad or slow song thats not too loud etc.... but you want a stick with some wieght on it that will carry when you are grooving or playing a song that is kind of loud. Go to a music store and try out several stick sizes and find one that is comfortable for you and if you have the money at the time buy more than one pair thats different sizes and start a stick collection. I would look starting in the range of a 5A and go up from there. /then theres specialty sticks thats not really a size but fits a certain type of playing style for axample Vic Firth makes several jazz style sticks for jazz players, these might work for you quite well too. Just experement and see what works for you. Good luck to you dear i hope this helps. As far as brand i would go with Vic Firth they're a little higher in price than some others but by far are the best but Zildjians are good and of course the stick staple for years ProMark.
