The traditional way of thinking was that you needed more wood in the neck to have the best response. The modern way of thinking is that It’s more cost effective. I find the neck on my SE Hollowbody to be a little less wide and fat than my core guitars, and very well suited to my hands. The core Hollowbody I had felt the same.
My original question was looking for an answer as to why PRS doesn't offer a "Pattern Thin" in a full HB.
