Double Hand-Strap possible?!

Dear all,

This is mainly a question for Hand strap users, and it is NOT a recommend me a Hand Strap thread.

I want to buy a new camera, and I got a bit tired of using the Neckstrap, as my Neck does not like it too much, and I don't like it either, as it gets in the way a lot.

So I wanted to try a Hand-Strap.
I would buy a 5Ds, with battery grip, as I shoot a lot of Portraits.

The questionis:
Can I use 2 hand straps at the same time, 1 for the Grip, and one regular?!
As I would prefer to always have a "safety" mechanism, just in case, in both vertical, and horizontal position.

I don't know of any that would allow the use of 2 hand straps. When I used a hand strap the neck strap could also be attached - I found that a pretty good setup.

So you're wanting a hand strap for landscape mode and one that goes on the bottom for portrait? Not aware of any system for that. But if it's for safety, I like having a shoulder strap and a Vello hand strap (that's a copy of the discontinued Canon E1 hand strap for vertical grips). For shooting portrait, I don't have the hand grip, but it is pretty nice to have a sort of holster quick draw
