HB is a very durable buggy as you mentioned also Losi. I've driven a few buggies but the Serpent buggy has outlasted all my prior buggies as far as durability and wear.. It doesn't slop out fast and it take a beating and it keeps on ticking.. It's carbon fiber is also very strong. I'm currently running the Orginal towers on my ebuggy from last season. I've taken some big front hits. Pretty much all current named brand models taking the abuse but as far as wear it's not the same. Some buggies slop out fast and there drivetrain wear quickly..
