930 Headers: T304 vs 321 Preference

We have produced several sets of 930 headers now and I am evaluating pricing.
The price point that I wish to hold is a couple dollars more than the popular short tube headers currently on the market. My headers offer many advantages that increase cost and justify the sale price.

My question to you as enthusiasts is how much does weight vs materials matter?

We currently use 321 stainless as it has properties that work well in the turbo environment. T304 stainless is the industry standard but does not hold up as well to the heat and stress given the same wall thickness. You can compensate for this difference by increasing the wall thickness in the T304 which also increases weight.

It will be difficult to retain current pricing using light weight thin wall 321. What are your views given the choice of a heavier product (currently 15 pounds) or a more expensive (couple hundred dollars) product?
