I have always leaned toward aluminum bedding blocked stocks since acquiring my first TC Icon many years ago. The icon experience for me was that good. For me, I think a big reason for alum block or pillar bedding is to provide a consistent material to torque action screws against for repeatable reassembly stock pressure. Free floating the barrel is another, but too many folks still skim coat blocks for increased accuracy to think bedding blocks alone deliver optimum accuracy. Just my rationale, I do not claim to know thit from thynola in the grand scheme of bedding techniques.
