weight difference between IA1 and IA2?
 

anyone have any real data?

Depends on the bore size. Apples to Apples the IA II is 5 to 10 pounds heavier because the main webs are 1’’ wide (thick), the deck is thicker and the valley walls are thicker. All redesigned over the IA I block for improvements.

I talked to dick and he agrees about 5 pounds he said. thank you

I told you it was you!!!!!

Lol I'm svelte!
