meant to post this yesterday but fell asleep. played some doubles and 2 sets of singles yesterday with the 310 in stock form and then today with 2g of lead at 12, 3 and 9 with Yonex Premium Leather grip and overgrip.
I own Tour G 310s and have demoed the Duel G but didn't switch to it. I will make some comparisons to Tour G.
Strung it at 50lb using Klip Legend 17 uncoated in the mains and Yonex poly tour fire 17 in the crosses.
Initially I had some problems with the launch angle as I kept hitting shots in the net. Took abit of adjustment and then was hitting fine after that. it is definitely very underpowered in stock form so no wonder TW rated the power level at "low." All my shots lacked omph initially but with lead it really came alive, just like the Tour G 310. Plowthrough became much better and love the control you get with this stick.
The feel was great and has a nice flex at the throat. In terms of spin, I didn't really notice much of a difference between this and the Tour G even though the Tour G is 16x20. Spin isn't really this racquet's best attribute but it's generally adequate for most. I think where this racquet really shines is when you flatten your shot and when you attack the net as just like the Tour G, you get pinpoint accuracy. Maneuverability wise, it's similar to the Tour G. Feels abit more heavy than its specs would suggest but it's not that bad. The weight distribution is abit better with abit more weight spread over the whole hoop instead of concentrated at the throat like the Tour G.
Overall, it's definitely a great control stick for people who can generate their own power. I can't really say it's an improvement over the duel G considering I've only played with the Duel G once but I guess they feel quite similar. Definitely an improvement over the Tour G in terms of weight distribution and paintjob though. I've bought 4 and I think this will be my main stick for the next few years.
P.S the paintjob really looks awesome in real life and the blue section on one side of the racquet isn't bright at all. Both the blue section and dark orange really blends in with the navy frame. Also the 0.5mm reduction in beam width is noticeable in the hand. Does feel abit thinner and feels abit closer to my K90 from years back. Love those thin box beams.
