I finally "let go" and decided to just go with the list I have been honing for weeks now and so I know I won't have any more model issues to deal with due to last minute switch outs. No reason to make a last minute change and then regret it over the weekend.
I will have to rely on experience, average dice rolls, and Force weapon awareness.
It is slightly calming though, to just accept that I have prepared to the best of my ability and all that is left is to let the chips fall where they may.
I did not get my Wave Serpent done. I discovered that my school schedule for the week was the opposite of what I believed it to be. Plus side is, that I have all my work taken care of now and I can push it from my mind until after the GT.
