I have never had the Customs made, but I have used bothy the Acetal and Black Ravens. These are my favorite production picks- the Black Ravens have a better tone for bass, as it produces less attack and as a result a nicer tone in the low end with less "thack, thack, thack" noise you get with pick use than the Acetals. If it weren't for discovering Gravity picks and then subsequently V-Picks (the screamers are by far the best pick I have ever used!) the dozen Black Ravens I have sitting around would still be in use.
