I have a 2001 Stnd. that weighs in at 8 lbs. 10 oz. I played a new Stnd. in GC yesterday and I guess they're all chambered now - unless you go with a 'Traditional' which is weight-relieved (9-holes, a.k.a. 'swiss cheesed')... What's the general consensus on these two types of construction vs. neither option, which puts you in a Custom Historic I believe...?
