Cool. Thanks for the help.I found the Ultra Cable very comfortable... mine was strung in a Yonex RDiS 100 MP (16x19) @ 47 Mains/ 44 Crosses. This was a tad too low... still had plenty of directional and depth control as well as loads of spin, but could have been just a bit tighter. Next time I'll string the racquet at 48M/45C or 49M/46C.
The Black Code 4S is stiffer in comparison, but still comfortable.
Red Ghost is very comfortable, but I think the Ultra Cable is softer or more muted... they have a different feel. Because the Red Ghost is not as thick I can use it in more racquets.
What about Cyclone Tour? Have you tried it? Is it really softer than all of the above?
