The WHisker Biscuit original or even the new drop tine arrow rests are nice.
They hold your arrow in place at just about any angle, but you have to watch that you don't get the biscuit too tight or else it will chew up and warp fletchings. But personally i like mine alot. I usually ground stalk, and it is perfect for that.
