can anyone comment on the difference between the thickness and character of a US Authentic goat A2 and the less expensive not vegetable tanned Gibson Barnes A2s ? While I have recent samples from Shaul at US Authentic ..including the horsehide...since I have a US Authentic horsehide which is thicker and I think has more character than my US Wings horse A2 and my Legendary Schott HH moto jacket the samples do not show the differences ....thanks for any help or thoughts...
