You can have it all: strenth, adjustability, no bind, etc. RCC Specialty Products makes an adjustable M II strut rod that employs heim joints to eliminate bind. There is no picture on the website, but it looks very similar to the global west piece for early mustangs (see attached). Dwayne at RCC can email a pic of the unit. I have them on my car and am very happy with the performance.
