Best way to route the bowden tube?

My Rostock Delta Mini Pro instructions expect me to lay the geared extruder motor under the machine and have the bowden tube make a large circle loop.
however, it looks that the stiffness of the bowden tube will move the hot-end plate out of the horizontal pane, while travelling. Not sure if it will affect printing. I am not that far yet.

Also, putting the motor on top, will give tension at the tube's routing.

What is the best way to set this up ? How keep the tube as vertical as possible above the hotend during travel ?
Pictures ?

Here's how we do it on the Griffin Pro Mini, best method I have found yet for small deltas. Mount the extruder on top, then go out and around the vertical rail.
Oh, and I recommend you store the printer with the effector down, not at the top, this way the bowden stays stretched and not coiled up and flopping around.

Ok, makes sense.

My pre mounted bowden is pretty long, when I mount on top, I get a giant loop hanging around beside the construction, thus stressing the hot-end plate.
Shortening it seems necessary, but will also improve flow I guess ?

Some think having only one bend is best, but that's not always easy, and in my opinion, a shorter bowden is better if your extruder has enough power.

I prefer the S bend. Putting the extruder at the bottom with a soft bend and a good clamping. Then the final bend at the head. It seems to make sense to me instead of the top of the printer.
