Back in the day when I was actively involved in setting up FT natches, we tried numerous string holders. Most worked quite well, your stakes are a great idea, however, you need to cobsider the shooters and the pisitions they sit in. Are they left handed or right handed?? Some shooters didnt like others reaching over or around them when pulling the string, some wanted to pull their own while others wanted someone ekse to pull the strings. We were never able to come up with a suitable way to secure the reset string so everyone was satisfied!!! Good luck and will be loojing forward to seeing how well your idea works!!
