Cheaper and longer lasting as you wrote, lighter on parts and easier to bring to a stop as well.
Though I am spending time now lightening the load I just know that I will not have much time in the future to be maintaining a quivering animal.
An argument can be long standing on this, but in the long run, a more docile and civil engine will propel less weight easier with less tremor than an all out engine with more weight to burden with will do violently.
Maybe I'm getting old or just jealous of all those A-990s and 2 percenters. LOL.
