RC may/may not be a 'thing' but one thing laminated shafts do offer makers is the ability to quickly make shafts that will stay straight. Don't have to worry about long-term wood aging. I have two Mezz ld wood shafts and both are solid maple with a lightened front end. I can't tell any difference in feel/hit regardless of how i orient the butt in my hand. Rad. consist. is more marketing than reality imo.
