i did a three leading - three trailing lace on my front wheel. I haven't had to true it in 2 years i don't think. Same spoke length as 3 cross too, which makes it easy. You can see it in my sig

This is great guide for patterns. Has lot of ideas and info. At 160lbs I'd say look for 28-36 hole rear depending on pattern and 20-28 hole front again depending on pattern. Good ratio is 4 less spokes in front than in rear, although if they are the same it doesn't matter.
