Who it is for

Advancing and competitive players looking for hybrid with a medium response.

Why it works

Tecnifibre HDMX is a hybrid fibre construction string in 1.25 mm and 1.30 mm; the round profile gives it a predictable, even string bed.

Watch-outs

Softer strings move and fray sooner than polyester; expect more frequent restrings.
