I'm late at discovering the prince exo3 tour 100 3 months ago and just love that racket so I was very excited to try this racket out since it came from this line of rackets. Well first of all it is lighter then the exo3 tour 100 which makes sense because I think the "T" in the tourT 100 esp name comes from the team model which is always lighter. The lighter weight for me meant it felt great swinging freely on the forehand side but for the backhand it felt like it lacked plow thru. Whenever this happens then take out the lead tape for the quick fix rite!! So I added around 8 grams total to 3 and 9 o'clock which made the racket feel so much more solid. So the ESP technology? Yes I most definitely felt the extra spin and the ball cleared the net which was fun but on the downside I noticed that by day 2 of demoing that the strings have already notched a great deal so I wonder how long strings can last in this stick. By the end of the week I'm still not sure about this prince tourT esp but I'm having fun with it.
