Do you know when Lancair's beef up was made? Where can we find the 
suggested fix.

You may be so fast that you need the rudder but I am pretty happy using 
10* of flaps as my speed brake. This will take me from 150 kts to 120 
kts in a hurry. Based on Bill Harrelson's past calculations, this 
doesn't cause as much pressure on the flaps as does 40* at approach 
speeds.

I haven't inspected my plane yet. If there are any cracks that I can 
see, I will report them here on the list.
