Highpass it if needed. The more you listen to different techno the more you are bound to realize that lots of verb-tips don't apply to this kinda music.

Tracks by big names can be bathing in verb. I would almost say that the (over)usage of reverb is one of the absolute key-factors in getting a ''pro''-techno sound. As rhythmtech said: don't worry to much about it sounding natural.

Two different reverbs on sends - one short (room or something like it) and one long one should allow you to create a nice 3-d effect. I'd just not put to much and to long a reverb on kicks and deep bass.

For lots of people 300 Hz is a value at where reverb usage starts. below that maybe not and mono if aiming at vinyl compatibility.

That's all i can add.
