I keep two systems. Wear for 2 weeks and rotate. I will try and do the same when I get the full-cap. I am kinda nervous on the full cap as I will need to shave my head for it. I only have one coming at present. I didn't want to order 2 and have them both be wrong somewhere. So I ordered one had a stylist help me with the measurements and any changes thought the template needed. So I am hoping it works. I it as my current systems are about 18 months old and have color shifted bad.

A year is easy for me with 2 systems. I am hoping I can do the same with full-caps. I may try three of them and rotate. There will be a big span between the ages of each on them so will see.
