Wasn't the V-tail Bonanza back end modified at some stage, which put a stop to the breakups?
There is a big technical advantage in a V-tail: instead of three huge things dragging in the airflow, you have just two. No wonder the new SE jets are V-tails (Cirrus and Eclipse, IIRC). It's got to be worth 10-20kt, which at the relevant cruise TAS is worth an awful lot of fuel flow.
I bet you will notice when the yaw damper servo packs up though
