Wheel set consideration Background: I'm overhauling/refurbishing my second road bike that I use mainly for training. It needs new wheels.

I found a couple of nice used 2011 wheelsets that were spares for a women's bike team and saw very little use. The rear wheels are 28 spokes; I have a choice for the front wheels. Either 20 spoke or 24 spoke. What should I think about to make the choice? (clinchers)

I weigh 160lbs if that matters.
If the bike is used mostly for training, you'll probably want to give high priority to reliability. In general, more spokes is better than fewer both because they're stronger and also because they're easier to true; 2-cross (or 3-cross) spoke patterns will be stronger than radial or "mixed" spoke patterns (for example, radial on one side and 1x on the other); rims with eyelets will be stronger than rims without; clincher rims will give you more choice about heavy-duty or puncture-resistant tires and tubes than tubular rims; aluminium rims will be more cost-effective than carbon; standard round spokes will be easier to find replacements for (should you need them) than bladed spokes.
