I have had the opportunity to hit with the new E-Force Invasion in its final form and not a prototype. I can only comment on the Quadraform head shape because that was the only final product I was given to hit with. I am sure the Tri-Tear headshape will pretty much be consistent with what I report here because of my conversations with EF about how the racquets will be weighted. I use the Heatseeker 2.0 160 which I will use to compare it to the Invasion 160 in this review. I also had about 25 players of all different levels and who used different brands of racquets hit with the Invasion so I can also provide you with their consensus.
In my previous posts, I mentioned the cosmetics are eye catching and there is no change in my opinion. The group of players who hit with the racquet totally agreed and loved the carbon fibre accents on the red/white color scheme.
I asked EForce about whether the Invasion will have a different feel in terms of weighting in the head, middle, lower compared to the Heatseeker 2.0 and was told it will be pretty similar. What I did notice was that it was close but felt it was more center balanced but not much. Some players felt that the Heatseeker 2.0 Quadraform was a little to head heavy and you will be happy with the Invasion. It felt great just gripping it.
I hit with the Invasion Quad as delivered and did not re-string, just out of the box. As a personal preference, I like my strings with medium tension around 34 lbs. but with the new Invasion, I did not even feel the need to re-string the racquet because it felt incredible! I described my hitting experience with a prototype 170 Tri-Tear as "SWEET" and hitting with this final product Quad 160 has not changed my opinion! It is the "sweetest" racquet you will ever hit with! Extra power and extra control will be realized with this racquet! I can only describe my experience but I am absolutely sure you will agree with me when you hit with the Invasion.
The general consensus of the 25+ players called their hitting experience as "SOLID, POWER AND CONTROL, ABSOLUTELY NO VIBRATION, BEAUTIFUL, TOTALLY IMPRESSED, . . ." I could go on and on about their positive feedback. Some wanted to by this racquet on the spot!
You will definitely do not want to miss hitting with the Invasion because it will elevate your game no matter what level you are! Hope you enjoyed the review and please post your comments and questions!
