115 gallon conical ferment tank, need fittings input

[Pour Decisions]

Just picked up two of the Ace Rotomold 115 gallon conical tanks. These are screw on lid, full drain and came with stands. I'll need to replace the drain fittings and add valves etc. I'd also like to add a second drain which will be located higher up to allow the finished ferment be drained off without pulling the trub.

Anyone done this? Whats the ideal location for the upper valve? Should I  go with camlock fittings or triclamp? I'll be picking up up pump eventually and will have that fitted with the same connections.

Seeking input/advice.
