I jumped the gun and got the Bulldog from OKCVapes after watching the pbusardo review. It's my first RBA, and that first few hours with it I figured I'd wasted my money. I got really harsh, dry hits, and even the fuller vapes were just not living up to my expectations. I let it sit, frustrated, and an hour or two later I vaped on it again and it was absolutely great!
So, fast forward to today, it's my primary vape on a lavatube when I'm home. Just love the flavor, the volume of vapor, and all this is on the stock coil. I am planning to make a coil for it when the time comes, but after a little over a week this thing is still hitting fierce.
A good tip to know, and I had to poke around for, is to be sure to use the o-ring that comes with the Bulldog to position the body so the airhole points at the coil, not down along it. I'd also recommend not doing what I did and letting the atty sit long enough for the wick to become fully saturated. I think that was a majority of the reason I was getting such terrible performance right out of the gate.
