I'm 65.5" tall and female, so my numbers are waaaay off where you dudes are, but I'd go 138lbs 18-20% bodyfat. Easy to maintain with no drugs or dieting, and I keep a decently small waist at that size without my bras becoming loose.
Competition conditioning is cool, but it's not a look I want all year round, and it takes too much work to hold onto it.
