Stick to your 165's and 170's op.
I guess my point is that it's not negligible.
It all depends on the factors that I listed above. Given a choice (which the OP has decided to make) those factors should be considered. If needed, it may have to come down to terrain. If it's flat, go 165. If it's hilly, go 170. Still can't decide? Go 165. "Spin to Win".
