MAD Bypass Question

OK, I've been reading through a bunch of old postings on this subject, and it seems that many have run an 8AWG wire with a 12AWG fusible link from the alternator directly to the battery terminal on the starter solenoid - essentially running parallel wth the stock bulkhead wiring as I had proposed in my first post in this thread. I haven't seen where anyone is running the 2-wire/4-fuse setup that Dan proposed. I don't mind doing it that way if that is the best way to go.

Q: Is the 8AWG wire with a 12AWG fusible link really insufficient? What is the risk?

Q: If I am taking load off of the bulkhead connectors by running a parallel bypass, how then is the bulkhead still a problem (assuming it is in good condition)?

I will also be adding Crackedback's headlight relay harness. My goal is to reduce the load on the stock wiring. I prefer not to cut/splice any of the stock wiring if possible. I just want to eliminate the weaknesses in a manner that is safe.
