I Like Matmit, haven't used the Safari, but would think if you stick with Detech, Coiltek & Nel you would be safe. It seems everyone that uses them has good reviews of each brand. The issue is not many have multiple brands in similar sizes to use on the same machine.
I have a 4x6 Shooter for my V, a 5x8 Garrett for my ATPRO and a 6x8 SEF for my Etrac, all work as they should, just feel like I'm going nowhere fast with the 4x6. In my opinion I would strongly recommend a DD With any of the fore mentioned brands.
