OP didn't give the length of his hammock. The 5/6 = 83% ratio is in the middle of comfortable for most. YMMV due to preference differences and differences in stretch of the hammock. It is that stretch from loading that changes the hang angle.
Once you find an SRL length you like for a particular hmmk, the hang angle doesn't matter much (or at all?), unless it puts you too close to the ground when your are aboard.
