Thanks you Mrshosted. I will be introducing a post and slider for those who do not want to use a rear bag. Seems like a popular request. I will have some anodised prototypes back next week. Will post a pic. I will look into the adjustable pull lengths through an adjustable shoulder pad. Right now I need to get a couple of batches out of the door as people are wanting them and then I will get version 2 done.
