998 +20 D top pistons

[ManyMiniCoopers]

Hi, just purchased a set of plus 20 d top cooper pistons.
I wanted some advice as to whether these are a good piston to use or would I be better getting some more modern designed pistons from Keith Calvers website or similar.
It's going to be for a medium tuned 1000, using 270 piper cam and a suitably lightened bottom end.

Thanks

Your D Tops will be fine for a mildly tuned engine.
