If the foot is bent up, (or is it down, I forget) it forces you to mount the spring under the pawl which is much harder to do than if it's on top where you can see it through the hole as you slide the pin in place. I found it easier than I thought to fashion pawl springs from a stainless steel .012 guitar string. Just needed needle nose pliers and wire cutters. An advantage is being able to bend the foot in the direction you need for on top of the pawl mounting.
Workshops that employed master wheel builders used to have an old ***** tonk piano on the shop floor to balance the tension on the wheel by matching the harmonics with the a key on the piano .
Tapping each spoke to match a certain pitch to indicate balance around the wheel and whether a customer wanted a B flat, E major or an F minot pitch matching the tension for the wheel to match their road, track, path-racing or touring requirements. I suppose a guitar inspired musical pitch for your sprung pawls striking the planet cage ring gear might be considered a bit OTT by normal people but normal folk don't repair 60 year old IGHs.
