Thanks guys, :P
That day was a total reality check that I'm not 18 anymore.
But I was surprised that I could still drain the 3's, and get the 'ole George Gervin finger roll going. (Self agrandising moment, sorry lol )
I was doing the seated floor twist before in my "short" stretch routine, but more for my back than glutes, I see now though how I can put more emphasis back there. I've gotta start stretching better I guess, now that I'm closer to 30 than 20.
