G.O.A.T.
I'm not sure I'd say syns are for everyone, but I certainly agree with the strengths you cited.
Among monofilaments, 3 stand out from the rest for me:
1. Gosen OG-Sheep Micro Super JC (Jim Courier) 17 -- incredible combination of crisp response and liveliness (alas, discontinued...but none of us can understand why ).
2. Prince Original Synthetic Gut -- as TW says, "They're not kidding - this is the original synthetic gut. Despite all the years and advancements in technology, there's something unique about this string that's kept it going." I've come across racquets that are > 20 years old with POSG strings that play still play great.
3. Gosen OG-Sheep Micro Super 16L -- great combination of feel, pop, spin potential and comfort.
Just curious is syn gut the same with monofilament for you guys?
