TOPIC:

When using REW to EQ my speakers I have been told that I should pick a curve which is in the middle of the highs and lows on the curve. This would tame the peaks but leave the valleys. Why not just pick a curve at the bottom of all the valleys and then EQ by bringing everything down to flat? I realize that this would mean you have to crank up the volume quite a bit but if I have plenty of amplifier power why not? Is it a concern about noise floor or something else?

You really should ask the person who gave you that advice. However, my take is that it depends on what exactly the "valley's" are. If they are deep notches then no, don't set the target at the botto of those because they are too deep and the EQ won't be able to flatten that type of curve anyway. If the curve looks more like rolling hills, then there's probably no issue with setting the target near the bottom, and in fact I usually do that myself. As you say, it does also depend on whether there is enough gain in the system.
