iforce with nanogy 98 at 21lb. the high clear ,backhand clear is fantastic. Smashing power is darn good .better than vt70 .highly recommended.i think tension should be at 23 or 24
Of course when you say that " Smashing power is darn good .better than vt70 " thats a very personal quote.
Imho thats not true. I do own a VT70 and though sadly i dont own a I Force i've played with it. I felt that the power comparison was nowhere close especially due to the fact that this is a 5U version we are talking about.
The I-Force might be quicker if not the same as VT70 (I must say though VT70 is pretty darn quick). But in terms of power, I felt it was really lacking in that department. Clears and especially backhand clears for me were terrible compared to my VT70,80,ZF.
But then again thats just me, we are all different and play differently. I suggest go look for one that someones using in your local club/school and try it out first before you buy it. If everything dont work out for you, you can always go for the 4U version instead.
