Timely subject for me - I just got this yesterday. Get a chance to show it off now - LOL.
I haven't been able to keep my hands off it, and they're getting a little sore. I'm not really a conga player - just a dabbler.
Bought a full size conga and returned it. This one meets my requirements, and while it's the larger one, the tumba, it's still a lot lighter, and takes up a lot less space than a full size conga. I show it on a snare stand, but you can play it on your lap too. They advertise that you can carry it in a backpack. But while the playable head surface on this one is 12.5 inches, when you measure it at the widest area of the rim, including the bolt mount, it's close to 16 inches.
LP makes a similar one, and while they're both a little light on the deeper bass sound, I've tried them both and prefer the Pearl.
I've also got a set of bongos, so between these three, I can get what I'm after.
Never had a djembe, but I wouldn't mind picking one up some day.
