Velcro strap 22mm vs one comes with 955


I am thinking to get one from  ( (Abanen Hook and Loop Quick Dry Watch Band) which is almost same as Yooside one.

  • I know one comes with 955 is pretty good and wondering if velcro strap would be better for measuring HR correctly when long running/sprint/biking and so on.
  • Is there any other benefit I can get from velcro strap other than comfort ?
  • I am also wondering how often I need to wash the band.
  • Thinking to get two so that I can swap after each run and wondering if anyone is doing this. Because I am worried about smell from the band due to sweat.

Thank you
