Hey guys, Bought many strings to try out over the past few weeks and would like to share my experiences with you guys here. More reviews to come 【Kason C-62 Commendatory】 Gauge: 0.68mm Core: ?? Outer: ?? Coating: ?? All it is listed is 'POWERFUL MICRO FIBRE' sounds like a powerful kid eating monster. Tested on: YONEX ARC 10 Tension 28 x 30, Yonex 4 knots 2 months, 3 hours per week at least Benchmark: Yonex BG80 Review: 1) Stringing Very nice for stringers just like Kason C-60 due to the likely titanium coating on the outer core, glossy smooth finishing. 2) Gameplay This is in the same series as Kason C-60. Shock absorption is the type you would find for medium feeling strings such as Yonex BG66. Repulsion wise i can exactly compare this with similar gauge strings like BG80 as they are simply not positioned the same in the market. This is more repulsive than C-60 and has better control. Tension retention is considered fair, ~-2LB in a month of 2hrs a week at least. Conclusion Repulsion: 7.5/10 Durability: 8/10 (No signs of breakage after 2 months. I would say good for a .68mm) Hitting Sound: 8/10 Shock Absorption: 8/10 Control: 8/10 Feel: Medium feeling (Similar to BG66, harder than BG65) Tension Retention: Good (~-2LB in a month of 2hrs a week at least) You can't complain for the kind of price you can get this for. This is not as good as BG80 but if you are for recreational or school kids, this is ideal as it has decent repulsion, power and durability. All these for this meagre price, this is a steal.
