I've been using Ahead drum sticks for about three years now. I absolutely love them. In these three years, I had switched between Pro-Mark, Vater, and, most recently, the new Vic Firth Titan sticks, and I ALWAYS make my way back to the Ahead sticks.
Some things to know about these sticks:
1.) You get a lot more bang for your buck. You get louder shots and more bounce even at the softest of hits. That makes them really great for rolling, IMO.
2.) These won't work that well if you have a lot of other percussion equipment. The only other percussive element I have in my kit is a cowbell, and I must say that there's a bit of a difference between hitting it with a wood stick and hitting it with an Ahead stick. I, personally, always keep a pair of Titans around just for the cowbell because I really do prefer the wood sound on it. Everything else sounds great with them, though.
3.) I play really, really hard (like an 8/10 unless I'm playing live, which would usually be a 10/10 as long as I can keep the stamina up for it) and I've never broken a tom/snare head using these sticks. I've only broken rock band drum kits with these sticks, but that was just pure stupidity on my part.
4.) They will take a while to get used to. I would say after a week or two you should be golden.
5.) If you're a fan of wearing drumming gloves (I got the ones made by Ahead), you'll have a bad time, unless you wrap your stick up with some grip tape. Using the grip tape, though, can change a stick from a 7A to a 5A in terms of weight and feel, from my experience.
6.) Unless you play like a monster, you won't break them. I actually just broke my first pair of Ahead sticks a few weeks ago. I had owned those sticks for two years.
7.) They are absolutely worth every penny in just about every aspect you could possibly think of.
8.) I would recommend trying out a few different pairs before buying. I find that the feel of a Vic Firth 5A and an Ahead 5A have a few differences, so I would try to go to your local music shop and try to compare them to the sticks you prefer.
9.) They sound great on cymbals
10.) The covers are a huge advantage over every other type of stick out there. You can mess around and come up with different combinations of the taper and weight of the stick. These covers last a really long time too. I usually change mine about every 6 months, and it's great because the covers are usually under $10.
