I've never built a WCed rig but have 30+ years of automotive real world experience.
So I'll state my case in a direct fashion. There is no intent to be rude. I hope HW comments
on this post.
The squeeze together clamps that can be found at
http://www.performance-pcs.com/
should provide enough clamping force, plus they will not distort the hose. They are very reusable.
The stainless clamps found at hardware stores have sharp edges, bulky clamping screw
housings and are never round. Ppl tend to over tighten them and they will bind-up and
do the twist.

When I've been forced to use them, they are tightened first on a socket
to get a decent contour. Then put in service. Plus the threads are cut through the strap
and the hose will pooch out through these openings. Just bad all the way around for small
clamps. After 1"OD they seem to be OK. I dislike them with a passion for motorcycle work.

I can almost here it now...KRIPES!! They cost. Yes they are not cheap crap but consider.
They will not need to be installed over snug for a VG seal, the hoses will not be damaged in
anyway with proper use, they can be used many times, they look good and least of all,
bragging rights
