That MOP tackiness helped put Schecter on the map.
I think it was more the quality relative to price, as well as willingness to cater to smaller niches helped solidify them amongst the first tier of mainstream metal guitar brands.
I remember most complaining about the abalone but being perfectly content ignoring it given the price and specs at the time.
Also remember, LTD was putting abalone on everything at that time as well.
If I had to guess, I'd say the new ownership's preference for abalone matches that of their own previous signature guitars.
