Just wanted to post this here in the hope that it will help players who have sensitive elbows, or are looking for a good co-poly that will help prevent tennis elbow.
When I got tennis elbow, it was from playing with a Babolat Pure Aero 2016 and hybrid of Volkl Cyclone 16 / GOSM 16 at 45/49# for 2 years. Figuring the string setup was fine but the racquet was too stiff, I switched to Pro Kennex Black Ace (315) 2020 and Q+5 Pro racquets with no change in the string setup. I noticed a definite increase in dampening with the PK Kinetic system, but still experienced arm pain after playing.
Then I changed my strings to full bed multi-filament, Pros Pro Superior Gut (1.32 mm = 16g) at 55-60#. The soft string made a huge difference. Little to no arm pain after playing. But while playing with the string, I craved the return to co-poly because of all of the negatives of multi-filament that I experienced: 1) lower spin potential 2) lower durability (string breaks) 3) lower playability time due to string bed "locking" after around 2 weeks. However, I noticed a big advantage of softer strings in addition to comfort: easy string "pocketing", which to me, is the same as "feel". Basically, what feels like balls are held longer by the string bed, which greatly improved my backhand / forehand slices, and touch volleys at the net.
I tried a hybrid of PP Superior Gut with Volkl Cyclone, but did not notice any difference in string bed softness compared to VC/GOSM, and overall lower performance.
Another setup I tried was Tier One Firewire Boost 16 (Firewire/Ghost Wire hybrid) which I strung at 45/45#. I hated this setup. The string bed felt stiff. My arm felt tender after playing with it for a session (1.5 hours normally). Spin was very inconsistent. I think this is because it is fairly extreme in profile (triangular), but as some areas wear down, it generates less spin if you contact the ball there. Power was also very inconsistent. Some parts of the string bed seemed to play fairly dead, while other parts tended to launch the ball.
Finally, I tried Volkl Cyclone Tour 16 at 55# after reading about @g4driver 's extensive experience with the string. The first time I tried, I said to my self, "this is my holy grail of strings!" Basically, all of the advantages of co-poly AND multifilament in a single string, with no need to hybrid. I was shocked how soft the string bed felt, as soft as multifilament full-bed. I feel the same string pocketing, giving me excellent results with slices and touch volleys.
I agree with other reviewers that there seems to be a lot of softening of VCT with the first half-hour of play, which my Gamma tension tester registers as a loss of tension. However, after that break-in period, the feel is very consistent for a very long time. I have over 20 hours of hitting with the same string job, and only see a minimum of notching, and the playability is the same. Also, the loss of tension does not result an increase in trampoline effect.
I figured that there wasn't going to be another string that could give the same results. Then just last night, I cut out Firewire Boost from my other racquet, and put in Tier One Black Knight 16 at 55#. I played 1.5 hours with it today. Wow! Another "holy grail" string?! When I played with it, it felt indistinguishable from VCT 16. Soft as a multifilament, great ball pocketing, good spin potential. Very consistent stringbed. Absolutely no arm pain after playing.
I don't yet have enough hours on T1 Black Knight to know if it will have playability as long as VCT 16. VCT 16 is just outstanding from a playability standpoint, as I people say most co-poly strings are "dead" (lose too much elasticity) after 2-4 weeks. I have been playing with the same VCT16 string for 6 weeks now and still feel the strings have the perfect amount of liveliness. In comparison, when I played with the Volkl Cyclone/GOSM hybrid, I felt the need to restring at least every 4 weeks.
For reference, I play about 5-8 hours/week at around a 3.5-4.0 level and am 47 years old.
