Alternate hand straps

Hi, I have a 7D, along with the battery grip and Canon hand strap. I really like this combination and use it ~80% of the time.

The problem is; when I want a smaller setup, I don't mind taking the grip off, but having to remove the hand strap every time really isn't practical. Was wondering if anyone used any other hand strap that used a different mechanism to get on and off.

Thanks
