Throw over yokes

Can I get some opinions on using a throw over yoke for training? I'm
more concerned with high performance endorsements than I am instrument
ratings, however I am curious about using practicality of using a throw
over yoke for practice approaches under the hood. I read 61.31 (f) to
say that a high performance endorsement requires "training". I also
read 91.109 to require dual controls except for instrument training
when "the safety pilot has determined that the flight can be conducted
safely." So am I right in concluding that a high performance
endorsement cannot be attained using bonanza with a throw over yoke?
