Sorry for anonther question related to surfacing.
 
I learnt that a good pole sturcuture of a spline is important for building quality surface. I'm still confused about to what extent I should prioritize pole structure?
 
Below is a simplified example of reproducing a hand sketch curve. The two splines are almost of the same shape.
 
  • Top: 7 degree + 1 segment + not so good pole structure
  • Bottom:  4 degree + 4 segment + good pole structure
 
Roughly speaking, which one should I choose for surfacing?
 
Thanks!
