I would recommend tag metals by far, very strong. SRP metals makes a line of bars now also that are supposed to be an extra mm thicker than the tags even, but I don't know if they have what you're looking for. Rather than further back, look for bars that are narrower, you'll find out it will be what you're really looking for. I was looking for something taller and further back also, but the narrower width compensated for both characteristics. The style I chose was the rap 350 bend tag x2 bar, even though I have a warrior they worked awesome. The narrower width will bring your arms closer together, which will allow you to stand a little higher and further back. The bars will also be straighter, so your wrists will have a little less fatigue also.
