Colt45, I don't think you are wrong for useing regular fishing line, tippet is expensive. I use P-Line for my sinking lines instead of leader. I am not familiar with your type of fishing but if finnes is not an issue and you don't need taper, why not.
I use Frogs Hair and Orvis Flouro on my tapers (reason is they are smaller diameter than the fishing line and strong)
