I agree, no need to change it. Just keep it adjusted and check the shoe every now and then. The shoe (plastic piece under chain) has been known to break up under abuse (I've replaced mine once in 45,000 miles) and is only about 6 bucks.
The only limit to the other types of tensioner ( spring/ and oil filled) are the limit on HP. I think I have read the 100 HP/ TQ is the limit. We had one that would flatten on hard throttle on a 95 inch with SE heads and 257 cams. Smoked the inner/ outer case's as well as the primary drive unit. Comp sprocket/ chain and basket. Stock one works fine kepp it adjusted.
