What players say

Liked 4 sources

Weiss CANNON Ultra Cable is a shaped co-poly with sharp edges that reviewers and most customers rate highly for spin and control. Tennis Warehouse's playtest scored it 93 overall, with spin and control at 95 each and power low at 54. Customer opinion splits a bit: most praise its spin, control, and durability, but a minority call it too stiff, low on feel, or prone to losing tension quickly.

Best for

Big hitters with long, fast swings
Players chasing spin and control over power
Advanced and intermediate poly users
Players who restring often and want durability

Pros

High spin and control scores from the square profile with sharp edges
Many players report it lasts a long time before breaking
Firm, crisp feel that some testers found surprisingly comfortable at lower tension
Several long-term users call it a reliable go-to string

Cons

Low power output, a poor fit for players who need the string to generate pace
Stiff feel that beginners or players with compact strokes may find harsh
Average tension maintenance; some players notice control and spin fade after two to three weeks
A minority of reviewers found it inconsistent or got little extra spin from it
