I'm not too cramped, when in the drops, my arms are pretty much extended all the day with a slight bend.
I keep getting the urge to stretch out though, even in the very back of my saddle

I'm not too well informed about body geometry. (knee over toe at horizontal crank position, bent arms, saddle/bar drop, etc)
Is the only solution a longer stem then? I was thinking it might be aesthetically kinda funky.
