I hate to say but it seems that you got the 1. Gen. It was really fragile and pretty thin. Even ZM70 1. Gen was not as good as the 2. Gen. I used ZM62 2nd Gen. up to 32lbs and didn't broke it within a week. Tbh I play only feathers and rarely mishit. A friend of mine broke ZM62 2nd Gen. within 3 days @30 on a mishit. IMO it is not fair to judge a string just by durabilty. Especially if it is pretty thin. I broke thin strings (0.65, 0.66) also after 3-4 days @32lbs due a mishit. According to your user name you are 15-16 yo. So do play with plastics? This could be the culprit for your experience at 24-26lbs. Why do you pay higher labour if you use a ZM?
That's because ZM string being so much cheaper than Yonex (say $5 vs 10), the labour itself (say $10) will seem relatively higher when stringing ZM vs Yonex.
So this means: $10 (Yonex string) + $10 (labour) = $20 $5 (Zymax string) + $10 (labour) = $15 right? Or do you guys have a weird price list? BTW CAD or USD?
7USD for a restring with Zymax62 is a pretty decent price. If somebody grumble about this "high costs" after 2 hours of play with such a thin string, what does such a person say about the costs for feathers for 2 hours?
I've had a quick mosey through the thread, but can anyone give a brief overview of ZM66 Fire Power? I've tried all the other ZM Fire strings but this one was news to me when a client asked about it. Is it significantly different/better/worse than the others in the range?
IMO, 66F/P is classic "middle child" syndrome - lacks the power and feel of the 62 and the durability of the 69. Or, for the optimists, it lacks the deadness of 69 and the breakability of 62. Pretty much exactly like the 67 in the old line-up, actually.
TLDR: Did not prefer ZM66FP when I first tested it. Then 3 days ago strung one up to retest and absolutely love it. Cannot figure out why the string the changed so much but will continue to test it and try to figure it out. In the mean time, it's my favorite and go to string. Ironic you mention ZM66 FP... ...Three days ago this Dink strung up a racket to test 66FP as Steve Crandall of Ashaway said 66FP has been hugely successful in Europe and parts Asian and wanted me to retest it. He told me to crank up the tension to suit my liking. The first time I tested 66 Fire Power (way back when it first came out) I recalled it was a bit numb, lacked power and some feel relative to the other ZF string... ...Dink has been using ZM62F at 33lbs. as of late and decided to go 34lbs. on ZF66FP... ...After 3 test trials, I don't want to say the string is amazing but IT'S AMAZING!!! It 34lbs., it's crisp, powerful, responsive, it's ideal for me. I'm not sure why, is it because of the increased tension? Last time I tested 66FP at 30lbs. Does a 4lbs. increase make that much difference? Did Ashaway reformulate/improve something? What's going on? I'll test it some more tonight but this string is a revelation for me. I cannot find any flaws with it and it will be my new go to string if things do not change.
Update: Not 5 minutes after my post, already had a person ask me for more details... Additionally: this ZyMax 66 Fire Power mystery has really intrigued Dink so we (my test crew/friends) strung up 2 other rackets with ZM66FP (at varying tensions) to test (tonight). More details: Racket: Ultra Pro PT (86.5g, BP~300, Stiffness: 8.0-8.3) String: ZyMax Fire Power 66 Color: White Tension: 34.0lbs. Other set-ups to be tested: Racket: Ultra Pro PT (85.0g, BP~295, Stiffness: 8.0-8.3) String: ZyMax Fire Power 66 Color: White Tension: 29.0lbs. Racket: Precision Pro 2 (84.0g, BP~295) String: ZyMax Fire Power 66 Color: Orange Tension: 25.0lbs.
What's the difference between the 66 Fire and the 66 Fire Power? Everyone seems to be comparing the 66FP to the 62 Fire and 69 Fire and coming to the same conclusions people did about the standard 66 Fire (well, other than Dink who's obviously loving it).
Yep. It's one area the Zymaxes hit the bullseye, for me: you go mental with the tension, and they reward you for it. I had 62F at 34 and it went absolutely beserk - shouldn't have survived the string job, never mind me kicking it in the bollocks for 20 hrs with plastic shuttles.
Odd session today. 69f at 26x26 was REALLY repulsive. Its never felt this nice. I don't know whether its just good synergy with the racquet (tpro) and my swing today, or just fresh string. Hopefully its the square tension that's done it and I will continue to string square.
I recently swapped to the ZM 69F at 30/32. Coming from a NS880 it was quite a big change, because the ZM69F doesnt feel quite as hard but much more repulsive. I feel that the ZM69F offers much more feel and control on the shuttle compared to the NS880.
Update: tested ZM66FP at 30lbs. and 34lbs. (dropped a bit after it settled down) At 30lbs. it's really good as well. It's relatively crisp, it's repulsive and more powerful (easier to generate power) than at 34lbs. (which of course, is to be expected). But the feel and crispness at 34lbs. cannot be denied. Dink loves it and prefers 34lbs. We didn't try 25lbs. yet. Regardless of tension (so far), ZM66FP is really, really good. More testing including 25lbs. later on this week.
