Ok now what?

I am running 5.2.12. I want to upgrade. This is a major pain because of the customization I have done and the 5.2.13 upgrade seems to modify 90% of the WHMCS files. Now I see there is a 5.2.14 patch as well. Should I wait for the dust to settle and do the 5.2.15 upgrade? 5.2.16?
This is frustrating!
