OK guys, yesterday I've tested the Big Ace Micro on my racquets and I'm amazed how soft this string is.
I've dropped the tension a bit from my old stringjob( BA 1.22mm mains @ 59 and Maxim Touch @ 63 crosses ), and it's perfect.
I'm really impressed how soft and comfortable this string is, since I couldn't use a full poly stringjob before, but I had absolutely no problems using this one. I'm sure that the tension drop helped a bit, but I think that I couldn't use any other full poly stringjob.
Spin is fairly better than the regular BA 1.22mm, and the best part is that BA Micro feels as solid as the regular BA, with much more feel and pop. It's great how this string doesn't have the characteristic dull and dead feeling from polys, being much more syn gut like. It doesn't move at all, and it's perfect for 18x20 string patterns( my case ). I used a lot of slice serves, and adding the fact that I was playing on a hard court to it, my hitting partner had a lot of problems returning them. I was very pleased, because I don't practice that often anymore since I did when I was younger, so my slice serves are unconsistent.
Also, it's slitghtly more powerful than BA 1.22mm, what also suits my game, since I'm a weekend competitive player, with long swings, but with no time to work at the gym to be able to handle full low-powered poly stringjobs.
So, I end up getting the best( for me ) from syn gut world and poly world: comfort, feel and power( everything not as like, but similar or fairly close to ) from syn guts and control, no string movement and better spin from polys.
I'm glad I bought two reels of it. The only aspect I couldn't check yet is durability, but it's not a big issue for me, since I'm not a heavy string breaker and I don't play several times a week, so I'll even enjoy if it breaks before going dead.
Cheers!
