Heavy boots break your body down slow, and knees don't grow back once they're shot.

So was the green kid diving the tables or were you just babysitting him while he played chamber operator? You basically paid 15 minutes of saved time with 20 minutes of pure stress, and that's a terrible trade every single time.

Man, it's a $99 lens and you got one decent shot, that's not exactly a reason to overhaul your whole setup. Shoot it like that for a few months first and see if stacking is still working for you before you go buying a tracker.
