If minimal weight is what you want, you will have to say so. Many custom builders have their "hook" that gets you to pay attention to their rod and hopefully ache to own one. For me, it is the military ribbon wraps and my grips. I know I have a buyer hooked when he/she gently takes a rod in hand and fondles the grip or when a Vet's eyes get a bit moist seeing his decorations on his rod. An emotional relationship has just been forged with the rod that a few grams can't break.
Discussions on weight produce interesting discussion but it is still my opinion that when looked at in a logical manner a person should be more concerned with balance as the weight differences even between an IM6 blank and a Sage One blank are minuscule. The first can be made to feel divine in hand with proper balance and that Sage One can feel like a club if not balanced well.
