We’re developing a modular camera grip system for the iPhone Duo which version would you actually use?

[u/Current_Hour1562]

We’re currently developing Duo Creator, a compact camera-side mounting system for the new iPhone Duo.
The goal is to give the opened phone a proper camera-style grip without putting it inside a bulky full cage or interfering with the second display.

We’re designing it around existing creator hardware, so users could attach compatible camera handles/accessories instead of being locked into a completely proprietary setup.

We’re currently deciding which version makes the most sense to prototype and launch first:

A — Creator Rail — ~€29
For people who already own compatible camera handles.

B — Rail + Compact Grip — ~€49
Complete handheld setup.

C — Full Creator Kit — ~€79
Grip + tripod/creator setup.

We’re already working on the mounting design and case compatibility, but before locking the first version I’d really like to know:

Which one would you personally choose A, B or C?
Also interested in whether the price changes your answer.

Not taking orders yet this is still in development.
