MAD ammeter bypass question

Thanks all. I will have to decide which way to go.....probably not my biggest problem these days :) I'm not too worried about aesthetics as I can hide most of the wire and the fuse fairly well. The idea of running all the current through the firewall has never made sense to me. I read up a bit on fuses vs fusible links since its not an area I have delved into much. Fusible links, although crude devices, have some advantages in certain applications like when the load might be high momentarily. They also have less connection points. Perhaps the slow blow fuses provide the same sort of protection. For example the MAX20 fuse protects for current over 20 amps but can take 30 amps for 20 seconds. That seems like it should work.
