May I please echo the other cries of NO! and add:

perhaps the problem was in asking "the best" of something, anything, 
anywhere. That is usually doomed to failure by drowning in a sea of 
mutually contradictory opinions...

I believe the approach you first posited was a perfectly viable one, and 
has the great merit of being one you understand well. 

I am also learning Ada (though after C and C++ it feels more like healing 
to me) and typically I'll write mostly what I am familiar with : picking 
and learning ONE new technique in the process : such as using generics 
for your callbacks.

Best will come in time; meanwhile, I am satisfied with good enough, and 
learning one step at a time.

Hoping not to discourage,
