Why unwind? Because Dan commits the desecration of reusing wire. And believe me, he isn't lacking for funds....lol He has just always had the habit.
Why Aluminum? He would say.... Why not?
He thinks there is way too much focus on the idea of only using copper. He'll tell you that while you may have to apply a bit more wire, you will be able to get it on easier with aluminum.
He believes with great conviction that there isn't any significant benefit to be had with using copper.
He is actually completely perplexed by the rejection of aluminum wire by traditionalists, and especially in regards to showing. But that's a whole different conversation. Can you tell he covered this at length
? (laugh)
Hope that answers your questions.
Kind regards,
