Do any of you folks with the extended ventral fin  have a picture you can share?

Thanks

I'm another 235/320 driver that added the ventral fin that extends the length of the rudder.  I did not add the trailing edge full length.

So far, I've had enough rudder to maintain runway heading using the gradual throttle (as I too was taught many years ago).  Use caution and apply rudder quickly on a go around as this caused an unwanted left turn recently.. I blame not paying attention...seeing the windscreen fill with tree tops brought me back to reality!

I did as Gary described but also added 3" to the trailing edge of the rudder full length.
I can nail the power on take off and have no trouble keeping the airplane heading down the center line.
FWIW,
I was taught to add power gradually which I do, usually anyway...
