  This was an old post but I just now got around to looking at a 
Decathlon. I have only flown an old 7ECA and I wanted to make sure 
that Decathlons had the same setup. On Pitts and Eagles the need for 
a little right rudder during cruise is taken care of with a trim tab 
on the rudder. Some Decathlons have a rudder trim tab, but some do 
not. On all of them the main thing that takes care of the problem is 
that the bottom front of the vertical stabilizer is offset to the 
left. This means that with the rudder centered it is like having some 
right rudder in. It also means at full deflection the rudder is more 
effective to the right.
