(TMI warning, right here and now)
I prefer Brazillian waxing (but oy! the expense!)... but have them leave either a small triangle on top or a strip depending on my mood. Then I personally trim the remaining hair on the triangle with scissors to keep it around 1/2 inch long. Women's pubic hair comes in all different types. Some is very long, some is very short... some curls, some is straight... it all depends. My personal preference is short, so I keep mine that way. It's my V, I keep it how I like it. Everyone else be durned ;)
When I can't wax, I trim 90% of the time (the other 10% I shave). I use (don't laugh) an electric beard and mustaches shaper I stole from my husband. The kind that's not "trimmers" that you cut hair with, but the kind you can put on your hand and not cut yourself with. (I've made the mistake of using trimmers/clippers and those cut...oweeeee... too many curves!!) Same token, I leave a strip or triangle on top. If I'm feeling perky I might try another shape (hearts are easy...it's just a triangle with a V on the top of it, lightening bolts look weird... thanks SintheS :P). The only time I've ever gone completely bare was on accident. (Hey! It's hard getting things "even" working upside down or in a mirror!). But aesthetically I prefer a triangle.
I used to shave smooth (not on the top)... and for those who do... Secret Unscented Solid Deodorant/Antiperspirant. Just swipe it on any shaved area as soon as you've finished shaving, including any and all shave girlie parts as well as your inner thigh/ bikini line. For some reason, it's consensus that THAT is the brand to use (Ph balanced for a woman, maybe?)... because it, hands down, works the best to prevent chafing, razor burn, bumps and ingrown hairs. Just be warned... you do NOT want deodorant/antiperspirant on your tongue. So if you're getting oral regularly, waxing or trimming is recommended over shaving+Secret.
I agree though... Our V's are OURS. Mine, mine, mine, mine. While I have and would experiment for a partner, when you get to the bottom line, it's our body. Keep it how you like. I've seen thousands of women naked (for me job). As usual in the hair dept. blondes and redheads seem to have it the "easiest", as in whatever they do looks grand, and brunettes have it harder. But it's YOUR body. Do what makes YOU happy.
