search_stringsread-onlySearch 791 lab-measured tennis strings by name, brand, material and gauge, sorted by a measurement or by price. Each result carries stiffness (lb/in), tension loss (%), energy return (%), spin potential, ball bite and string friction, each with its percentile in the database, plus the current retail price, a buy link and the StringSpec page. Returns at most 10 strings; narrow the filters rather th
get_stringread-onlyEverything StringSpec has on one string, found by name (misspellings and missing gauges are fine): every measurement with its database percentile, elongation at 40, 51 and 62 lb, an estimated playable life, a tension adjustment versus the player's usual, how it ranks for each playing need (spin, comfort, control, power, tension hold, durability, feel), the closest alternatives, the retail price an
compare_stringsread-onlySide-by-side measurements, percentiles, prices and buy links for 2 or 3 strings by name, with the StringSpec comparison page when there are two.
