head oval and head square rackets, got any different interm of power and control??? IF the stiffness, weight order, n string tension....... are same.

If racket,string & tension are identical:

(Oval) more solid feel when smashing from the small sweet spot area, the power is more focused or 'pekat'

(Iso) more forgiving when smashing off-center sweet spot, smashing feeling not so concentrated/pekat and it is more spread-around the sweet spot area.

With Ovals, I can also tell exactly where the shuttle contacted the string bed giving me the feedback I need for any adjustments.
