Hello! I am interested in the the avantages and disavantages (scratch, mosityre and stain resistance, wear resistance and the list goes on) of various scales materials: exotic woods (cocobolo, ebony, snakewood, thuya wood etc.), synthetic (micarta, silicone etc.), horn. For example: Mother of Pearl scales are looking very nice but there are very expensive and quite brittle (hard to maintain). . . . Thank you very much
