Heater and Ac hose routing

[fishface]

Hi, I am finally getting to the point of routing these hoses and looking for the cleanest look. This is on my 69 Camaro with the Concept One accy drive which has Ac ports low on the compressor. I have seen the hoses clamped on top of the wheel well on the engine side as well as in the opening between fender and top of wheel well. Any pros/cons to running them there?? Also, what is the typical routing for the heater hoses?? Any help appreciated.
