Welcome to the forums.
The Vac-Hanger will be more specific to hanging heavier weight but also having the option to wear with lighter traction for extended periods of time like the PF. The kit quality overall will be on par but of a far superior design. I would definitely wait but if you don’t mind spending more money to get what will become your primary device then it wouldn’t matter if you purchase now what you will not use later. Currently, we are being held up due to the travel restrictions preventing access to the factory so that I can handle the final production and kit assembly myself in person.
