Work hardened aluminum tubing increases the chance for cracks and loss
of H-5606 in proximity to hot brake calipers and rotors. The Flex line
at that connection helps to improve safety.
On a recent rebuilt "after incident" on an RV-12 we made just that mod.
No regrets. Aircraft is back better than ever. The skill of easily
learning proper elbow bending of 5052 is no different than 3003. The
3003 is cheaper and easier to ship. If that is your priority, then you
can understand the selection choice.
Countless stories of the nylaflow lines make them a less than
appropriate alternative....IMHO.

I will be doing the same. Due to the massive flexing of the gear lag I
think the Flix lines will last much better than any hard line will. And
the
Flex of the gear legs will never become an issue at all.
But I will do all hard lines as per plans just with 5052 lines not 3003
lines. Probably Branco flex lines on the brake systems where needed to.
Those plastic lines shoe not be allowed on the plane at all.

I used .035" wall thickness on fuel and brake lines. Est what you'll
need
then order 2 ea extra 6' lengths of each size. Shipping is higher on the
long boxes. I purcased ss/teflon flex brake line set from Bonaco.
