My intention is use both belts. There are 2 main ideas behind my wish:
The first one is that when I turn 18 years old, I will can use much more the belt that nowadays, and as Catherine say, may be a good point to have two belts in order to change the pressure points.
Secondly, I have to admit I like the belts, for me they are nice, and I want a hip belt with ,I hope, cable rear.
Maybe can be good if the hip belt allows me a little more of flexibility.
My only fear is that can result a bit painful in my hips in add to the little pain I expect the first weeks of use in the tailbone, It seems be this way reading other girls experiences.
