If you aren't super confident about pattern and building, consider going 24/28 for better build tolerances and stiffer wheel for all your out-of-saddle climbing.
consider going 24/28 for better build tolerances and stiffer wheel
A 16:8 24-spoke wheel will actually be stiffer (axially, which is what matters, torsionally which hardly matters but doesn't hurt, and not radially which might actually be a benefit) than 14:14 28-spoke one.
