The Tomahawk has it's many admirers and perhaps a somewhat greater number of detractors. In my opinion, it is a sporty little plane, can be a bit twitchy to fly and demands the acquisition of fairly precise handling skills from the pilot.
This in itself is a useful exercise for students but it does require an instructor who is quite familiar with the type.
As a 2 seat trainer it's hard to beat but as a tourer it would be akin to choosing a kitchen stool to read the Sunday papers rather than a comfortable armchair. The PA 28 is both an excellent trainer and, if decently equipped, makes a good touring aircraft.
However the 172, in my opinion, makes a better tourer but it's baby brother the 152 is beaten into second place as a 2 seat trainer by the PA 38.
In summary, best of both worlds for me would be a traumahawk and a 172.
