Thanks for the replies.
I was expecting replacing with walnut would save 1/2 a pound in weight 3/4 max. If it could reduce the weight by as much as 2 pound it would be a no brainer does anyone know the true difference, i guess i could check the air arms site.
I actually like beech and some have great gain and pattern.
As for custom stocks not only out of budget but for me not necessary as i don't think you can beat the standard stock design although my old TX mk2 was the best gun I've ever handled.
