Looking to upgrade my timing chain tensioner to an aftermarket auto type on my 900 XP. Reason for the change is cold start rattle.

Looking into Weller racing tensioner which seems to be an improved hydraulic type, also looking into boondockers or Albas, which are mechanical type.

Wondering if I could get some input from someone who has one of these installed or knows more about them. What one would be the best and why?

Thanks for the input.
