Bearlkr! I've heard of a few stories about these problem's from others on this sight .I was going to purchase some for myself but after reading the thread's I decided against them for these exact reason's .I think you need to know exactly what your doing when you cut and apply the insert's with these arrow's and it wouldn't take much to make a mess of them .I think if you spoke with Jeff B about this he might be able to explain the problems with these arrow's better.
