Fuel line or hose for efi?

I'm planning my fuel line situation and am undecided with running all "rubber" hoses or hard line (aluminum?) w/rubber connections. Is one better than the other?

If it matters, I have an under bed tank with in-tank pump while running a turbo'd 292 with a Holley Super Sniper in a '66 GMC 4x4.

Thanks!

I ran -6an for fuel and auto trans cooling lines. Flexible line is far more forgiving when routing.

30R9 rubber line is used for fuel injection.

It may not be the correct way, but on my EFI conversion, I used -6 Push Loc fuel line from the tank to the TB..
