I've thought about hard lines but I'd be concerned about vibration and fatigue.

I had some of this stuff laying around from turbo projects so I used it on the end of the steel drain tubes coming from the heads.
OEM quality, designed specifically to drain oil properly, no vibration issues. No bulky hoses and fittings. Oval flanges easily welded onto a steel pan.
Tubes bolt on to flanges and use proper o-rings. Aluminum flanges could be welded on an aluminum pan. Nice smooth bends and big drain holes.
