Reviews

Power: 9/10 Control: 9.5/10 Defense: 8.5/10 Maneuverability: 8.5/10 Feel: 9.5/10
Pros : Excellent control and feel with above average power (the 3 parameters of a great singles racquet). The racquet is rather light at 3U- weight making it manoeuvrable and good in defence.
Cons: Price, as it is one of the costliest racquet in the market. Not suitable for beginners. Slightly smaller sweetspot and different kickpoint.
Suitability: aggressive attacking, all-around and control players. Need skill level of at least intermediate/advanced. Not suitable for beginners or defensive players. More details, please visit: http://badmintan.blogspot.com.au/2011/07/gosen-ryoga-issen-review.html
