I have both....stiff webbing and soft webbing. There are trade offs...yes the stiff webbing is easier to push through the slots but the D rings and such it's harder for them to secure them without a gap. The soft ones I usually have to use something to "pull" them through vs "push" them through. They wrap around accessories very nicely and are more comfortable when wearing a 3mm or skin. The stiff webbing is fine with 5mm and thicker and is easier to don without the flimsiness...so travel BC has soft webbing and my cold water BP/W has stiffer webbingThis brings up a question that I've had for awhile. I've seen mention of too stiff, too soft and Goldilocks webbing. I have been known to cuss at the webbing that came with my unit because it is SOOO stiff. But what is a good texture (wrong word, I know, but best I could come up with on the fly) for working with when assembling a back plate? Does too soft mean that it's hard to thread through the slots?
Slight hijack, but OP may find it useful if they decide to put together their own.
Thanks
