I also have the Tek3's and have my primary and lp inflator hose for my wings on the right post. I have my backup, SPG and drysuit inflator on my left post.
That's how I set it up. I will probably get a shoter LPI hose than the one provided with my wing. I think I'll probably switch the hose on the other side on my secondary and not loop it behind my neck. Seems like it would put unneeded stress on the hose, and since the XTX regs are reversible, I don't see why not. It would still run form the back up post.
