I finally got some 1/0 lugs in, Thank you Windy nation for a great price and fast shipping.
First thing is I was completely off base when I said the #50 was too small. I tried using a #70 first and it barely touched the lug. The #50 did a beautiful job without having to rotate the lug to avoid earing.
With a light touch the $6 HR wire cutters strip the insulation off the 1/0 in a heartbeat.
So even though I got the 16 ton tool by mistake, I'd have to believe the 12 ton I ordered would have done as well as it went up to #120. For under $40 it will make the numerous lugs I have crimp a lot easier.
