I'll give you point #1. The more you practice it, the easier it becomes though.
#2-They have suitcase weights for this that work very well. If I'm doing field work, the loader comes off and the weights go on.
#3-I can see how you justify this, but if you are ok with wearing your loader pins out by bouncing around a light duty loader then by all means.
#4-I was not calling you foolish, I was calling the act foolish. These modern loaders are very expensive and are not tolerant of abuse. Bouncing around a rough field is a sure way to need a line boring job done much sooner rather than later.
Its your equipment though, do as you wish.
