Hey there,i have couple of questions which confuse me a lot

1.have u guys actually heard of crazy horse rought out? I took it as crazy horse flesh reversed instead of full grain (which what it should be).if my thoughts are right what are the unique of one to the others and which are better for boots

2.which brings me to the next question,if rough out are the reverse part of full grain do they need to be lined again?or the grain are more than enough

3.i heard that suede are the cheapest flesh material out there (since it tooks from geunuine leather flesh,cmiiw)compare to nubuck and RO,are suede come with lining or maybe what i should ask is if suede needed to be lined

I really appreciate the answer,have a good day yall
