Verve Soft in short
Gamma Verve Soft uses AMP co-extrusion technology to combine stiff and soft materials for hard hitters wanting power, control, and forgiveness. Three protruding filaments provide maximum ball bite for greater spin generation. The co-extrusion build creates incredibly satisfying and heavy groundstrokes with super reliable directional input. Players describe it as encouraging, rewarding, and strengthening shots with raised intensity.
Sidewinder in short
Gosen Sidewinder is twisted during extrusion, which gives it a textured shape for more ball bite. Tennis Warehouse calls it one of the most arm-friendly co-polys on the market, and it has one of the lowest stiffness readings for a co-poly in the TWU database. The twist adds spin and control. Like many soft polys it loses tension at a fair rate, so plan regular restrings.
