Retro vs Reaper Watts. 75 vs 30

All of my speakers are on the higher end side of Watts.  ET65, Veteran, Invader and Reaper HP.My Ampeg VT60 (with ET 65) is a bit dark and the Retro may be the perfect speaker in a 1X12 Cab feed, that is if I didn't already have so many Wattages.For a 60 Watt Amp, a 30 W speaker like the Repaer is perfect becasue I have two feeds, one with ET 65 and an empty 1X12 Cab to be filled with either Retro or Repaer.  But to reiterate, the Amp is on the darker side.Should I be concerned about Watts??  I'm no tone guru, either and just happy with what works.
