As my I hurt using VS850 @ 28 lbs, I would like to try thinner string at lower tension and have some questions:
1. Why is Zymax 65 endorsed as "higher repulsion" than Zymax 62? Isn't thinner = better repulsion?
2. What are the main differences between Lining AP62+ and Zymax 62? Which is better for repulsion?
3. Do these thin strings play well at 22 lbs? How about 20 lbs?
1. You have to remember that repulsion and power isnt the same thing.
Thicker strings often have more power, where as thinner strings have more repulsion.
The differcnce is how long the shuttle lays in the stringbed, on thick strings the shuttle lays a little longer giving it more "power".
On thin strings the shuttle lays shorter time, wich means more "rapid" power.
Thats why ZM65 is marked as highest power string out there, it has got the mix from both worlds.
ZM62 = AP62 while the AP62+ is a new version of AP62 with an extra thin layer of coating to increase its "extra-low durability" and most likely this coated string feels more slippery.
Logically speaking, slippery strings are more durable than the rough ones as they will have less friction during play time.
AP62/ZM62/AP62+ are definitely more repulsive than ZM65 under the same tension since they are thinner but the problem is, the recommended tension of those .62mm strings is < 25 lbs. If you play above the recommended tension, be prepared to bring some spare rackets and some $$ to spend for restringing after the session
For plastics, I would suggest thicker strings i.e. ZM65 even ZM67. However, for feather I think ZM62 or AP62 would fair better. But as others have/will say, ZM62 is prone to breakage. I would stick with ZM65 to be honest.
For me, I need high tension to play well with feather (opposite for plastics). Which means my string has to be durable at least at 25 lbs. Ideally, 27-28 lbs. would be better meaning ZM65 is my pick over anything thinner.
I've been using AP62 for over a month now, and that's 3 times a week on average of 2 hours each. I had it strung at 27.5lbs and it's yet to giveaway even after many monumental mishits. I've got Zymax 65s handy as replacement, and I'm going all out with smashes to expedite the process of replacing the strings. AP62 feels like it holds tension really well. I love the power and sound when you smash and drive hitting the sweet spot. I'll be stringing the Zymax 65s at similar tension to get a fair comparison, so stay tuned.
Zymax string (whether 62 or 65) is definitely better than AP62+ for me personally....it's durability also wins hands down. Too bad, my regular stringer dun have this string and I've gotta string it in JB....hehe :P
Just as I guessed, the AP62 gave away. I managed to have the last few points of my game for the day with the ZyMax 65, strung at 28lbs. It's unbelievably responsive. The repulsion is unlike any other. I may have found my second favorite badminton string. I don't think I'll ever use BG66 again, as long as I can get hold of Zymax 65. BG66 Ultimax is of course a different story. It has it's own sort of repulsion and control.
