he might have not liked TC100 in general rather than string on it's own (TC100 is very specific and not for everyone)
but feedback is not the main aspect about cyclone I agree.
You might enjoy string like Solinco Confidential and Mayami Tour Hex as they are shaped but are the bridges betweeen shaped and round.
Maybe there should be another group category "Bridges strings" with shaped profile but round feel and response ?
But it would be very hard to determine...
Bridge string to me is a string that have slightly higher spin potential than round profiles (you can accelerate faster without the fear of hitting out - too much power and not enough spin to bring the ball down) BUT the feel and response is more neutral, closer to round profiles.
With round profiles I noticed that I can finish my shot (racquet position) slightly higher because the effect of "grabbing the ball upwards" is smaller. Ball is more "sliding" and you finish very high but the ball is already off the stringbed YET your aggresive movement upwards can create spin but you have lower launch because there was no "grabbing" HA! sorry for making it sound so complicated...
to make it sound more simple:
shaped strings can create higher launch because they grab the ball up and then release it while round profiles don't grab that much there is more "sliding" effect. Maybe easier to frame the ball but the launch is less "explosive".
Again - just my experience and feel.
In fact I would say snapback will always win with shape in terms of spin potential BUT you need adequate racquet head speed to make it work. Both have their pros and cons. There are also some shaped strings with low launch angle...or you can use thicker gauges to lower the launch as well...
Nadal is using shaped string but in 1.35 gauge

I would put some money that his launch angle "experience" is similar to some 18x20 frames with 1.20 gauges. He just decides to shape the ball that way with aggresive acceleration.
16x19 with 1.35 vs 18x20 with 1.20....tricky question
ahh those options...
