in my opinion
what makes drop bars so good is not the one position where aerodynamics are optimized
but the fact that there are four or five positions to rotate between to keep yourself fresh
what worked for me to get comfortable in the drops
was to train myself to ride in the drops for short stints
every now and then
start with 30 seconds
work up to minute or more
then you wil have that position when you want to cruise into a headwind
or beat your personal best over some timed section of road
however
if you keep trying and just cannot get yourself comfortable
you can get a different stem with a little more rise or a little less extension
or both
