Prince ozone 4 vs 7

[alexbu]

Hi guys,

I need your advice.
I played tennis back in my yearly teens, and now after more than 10 years i am back to it.

I can't decide which racquet is better for me, the Prince Ozone seven or four.

Im 27 yo,
182 cm (about 6").
78 kg (about 170 lbs).

I would rate myself as a beginner+

Which of the racquets should i choose and why ?

thanks !
