these are considered low end rackets and they caught my eye because i've never owned a black knight and because they are on sale for under $50USD. while there are many rackets that goes under $50, not too many of them are full graphite or carbon graphite. for the power ray 35/45, they are both full graphite and one uses carbon 4 on the head frame the other uses HM graphite on the head frame.

my question is, how are they able to afford such material where it's usually found in high end rackets and how can such racket be so cheap with the 35 at $39.95 and the 45 at $44.95??? is it possible that there are different grades of carbon 4 carbon and HM graphite??
