Alright, I'm back after a good hitting session with the Lime and here are my collected thoughts. I used it stock with overgrip and dampner, no lead tape or weight anywhere. I will give thoughts on comparison with TC97 (18x20) first as that is my main stick and also K7 Red afterwards.
K7 Lime Strung Specs:
I know a few folk asked about these. Mine weighs 338.2 grams strung up with Hyper-G 17. The balance strung up is 312 mm or 10 points HL. Pretty headlight as I am generally used to 7-7.5 points HL strung in that static weight range.
First Impressions:
Fairly positive. Overall Lime is a stable and comfortable racquet. Power is okay but it definitely could use weight in hoop area. You need full swings for this racquet in stock form but since it is light and whippy, it moves through the air fast so should not be an issue if you like faster moving racquets. Off center hits were not jarring at all and it plays comfortable but it is most definitely not a sub 60 RA racquet, you can tell just by hitting. Low 60s RA is about right although will have to confirm once I have access to RDC. My timing, as expected, was completely off. I would correct myself and hit late to get timing right and then forget about it a few shots later and be early in my swing again. I am sure adding weight will solve it without any issues. I generally play with 330 swingweight. This felt like it was barely 320. Maybe between 315-320.
Comparison with V3 TC97 (18x20):
First comparison is with V3 TC97 (18x20) as I used TC97 as my main stick. I am comparing both racquets in stock form (TC97 is 310 with 9 points HL unstrung) and both racquets with Hyper-G 17. The K7 Lime is more comfortable and has a softer feedback on ball contact, although I have never felt uncomfortable with my TC97. Lime has a lower swingweight when you compare stock versus stock. It is more maneuverable as well and moves through the air quick. Launch angle for Lime is similar to TC97 (18x20). TC97 has more power and plow in stock form even though it is 5 grams less in static weight than stock Lime. I drive the ball more than I brush generally, and really appreciate that about my TC97 racquets. The biggest difference I noted immediately is the feedback and the flex upon ball contact. TC97 has a very clear hoop flex where you can feel racquet flexing in the hoop area upon contact. Very old school ala HEAD Prestige type. By contrast, K7 Lime has more of a uniform flex and not so much of a pronounced head flex. I don't want to compare here with TC95 here either because even though those 'D' beams have a uniform flex, Lime felt different than TC95 or TC100 probably because of much lower power and much lower launch angle. Also, ball sound upon contact. The 'thwack' sound of hitting the ball was absent in K7 Lime. I am guessing that typical Angell TC sound is because of foam filling.
Comparison with K7 Red:
I will be comparing this from memory as I already sold my K7 Red. K7 Red had less power and was definitely more softer and plusher feeling than K7 Lime. I had far greater control with K7 Lime than I had with K7 Red. K7 Red fluttered in stock form on off center hits and was not nearly as stable as K7 Lime. As most of you know, I was not a fan of K7 Red. Even after adding weight it just did not tickle my fancy. K7 Lime on the other hand is something I liked and may work with in the future if I'm in the mood for customization.
My Conclusion:
I could definitely make the K7 Lime work, but with my newish V3 TC97 (18x20) already in rotation, and now that I am finally playing well with them, I think I will wait a while and see how things pan out. No plans of switching just yet because my game will not improve if I switch to Lime and there wwasnt any outstanding enough feature in Lime to make me reconsider my TC97 racquets. But I will give Lime a nod of approval for sure. A superior racquet than K7 Red for my game.
