When Prince is referring to Extreme String Pattern, they are not joking around when referring to the Prince Premier 105 ESP. You have 14 mains and 16 crosses to play with, which is what several other raquets in the ESP line up also offers, but those racquets are only 100 square inches or below. The Prince Premier 105 ESP is a 105 square inch head size, so that is not a lot of string considering the head size. Anyone that liked the Prince Red racquets, but was wanting more spin will appreciate the Premier 105 ESP. It will take a lot of getting used to for the opponent, when you show up with this racquet for the first time.
This racquet still uses the EXO3 technology, so you benefit from the 26% increased energy transfer at ball impact compared to a traditional racquet and now you have up to 30% more spin from the ESP technology. This is a lot more demanding to deal with for the opponent and you are looking at a lot of free points.
