[Q] Spigen Neo Hybrid (SGP11120) Mulitple Q's topic

I'm thinking about getting the Spigen Neo Hybrid (SGP11120) and wondered if anyone could answer these questions.

1. People seem to be complaining about the difficulty in using the HRM with this case.
Would simply cutting away the material between the HRM and camera fix this issue? (yes I know it would void warranty etc).

2. If I were to buy the Choetech wireless charger kit http://www.amazon.com/CHOETECH-Wirel...dp/B00PUA06TA/
Would it work and charge with the case? And will the receiver fit into the case, it's 1.3mm thick. Or should I get a thinner receiver?

3. Car mounts: I'm thinking of buying this type of car mount clamping mechanism http://www.amazon.com/Aduro-Universa...dp/B008ALV0V4/ and using the phone in portrait orientation.
Not the actual mount displayed, but one that fits into a CD tray.
Would the sides of the case frame offer no grip and cause the phone to just slip down or would the grip of the clamp by sufficient?
Or should I be looking at mounts which have "feet" for the phone to rest on, instead of relying on just grip?
i.e. this type, even though it look big and ugly http://www.amazon.com/Mountek-nGroov...dp/B004G1L52Q/

4. Does the frame of the case (the none metal version) cause any reception problems (cell and GPS)?

5. Is the back of the case "grippy". I've heard the "Verus Iron Shield" is more grippy, doesn't have the HRM problems, but the people say the frame looses reception.


Thank you for any help.
