rob,
You have the same clutch plate as mine. They need to have a 'bedding in' period. I have no shudder at all, I can take off from idle in 2nd gear without kangaroo hop. You do have a very agressive 2500lb pressure plate tho, makes trying to slip the clutch a bit of an effort over stock.
The pressure plate is something you don't have to go othe top with and in return you get a very stock feel to your clutch, with great grab.
