Yes defintley a different feel when you go up an ounce in weight like that too.
The pro open felt solid in stock form for me, but I have leaded mine just a little and it changes the stick a little. It always has felt solid to me and never hollow though.
Coming from ur background You most likely prefer a heavier stick and would probably need the POpen leaded to your specs to really be into it.
Great screen name by the way..lol.
