Fuel line recommendations... Got a second-gen Camaro with full Speedtech Extreme suspension, LS427/570, T56, Rick's Tanks Restomod with ZL1 fuel pump, and VaporWorx PressureWorx ZL1/Universal PWM Fuel Module Controller. Gotta work out fuel lines. I spent some with on the phone with Carl from VaporWorx, which turned out to be an invaluable call, and he gave me some great recommendations. I'm just looking to get the hive mind's feedback as well. I was recommended hard lines all through the middle with flexible lines on the front and back. I spoke with Speedtech as well and they said do flexible lines through a lot of their cars. Some of the vendors I was recommended were Fragola, Goodridge, Classic Tube, and Pegasus.
At this point, the only thing I know is I'm using AN6 lines. I like the idea of bending my own hard lines, but I also like the idea of an easy install with flexible lines. I need to figure out if I'm doing flexible lines entirely or a combination of flexible and hard lines. What are you guys doing out there? Which products are you using for your tubes and fittings? What else do I need to take into consideration? Any and all feedback is very much welcomed.
Thank you!

You might consider Aeroquip Startlite fuel line with the fiber outer covering instead of stainless steel. Stainless is heavier and just a tad stiffer when bending.

Be aware that if you decide on PTFE hose that it is extremely stiff compared to the more flexible Aeroquip hose. If you have to route the hose and have tight corners and bends I prefer Aeroquip. The bend radius for -6AN is extremely tight. The hose uses normal AN fittings. The thing I don't like about PTFE hose is the large bend radius. And even if you can bend in a large arc (90 degrees) it creates pressure on the line because it want to remain straight. IMO with fuel pressure at 60 psi inside the hose as well you must secure it randomly while routing. Eventually I plan to remove some remaining PTFE hose and replace with the more flexible and easy to work with Aeroquip fiber (Nomax) outer liner Startlite Racing Hose.
That said there is also convoluted PTFE hose that is very flexible but very expensive. If you can afford it IMO the best solution. It's light weight and extremely pliable. The fittings for PTFE are different than normal AN fittings. You use an olive on the inner liner and if installed correctly you won't have any leaks.
With either type of hose the fittings are reusable except for the olive. Order extra olives if using PTFE, just in case you have to make some changes while routing the hose.
Tip: No matter which hose you get, buy an inexpensive jig to hold the fittings in a vise while connecting the hose to the fittings. Make sure to blow out the line when cutting either PTFE or Aeroquip if using a Dremel cut off wheel to cut the hose. Crud from the wheel accumulates inside the hose and you don't notice it after each cut. Blow it out with air.
If you decide to use hard and soft lines it will be more costly at each connection between both types because of the cost of the fittings to make the join. In addition each connection is an additional source for leaks. Keep it simple with fewer connections.
