Was able to get together with a local 501st member and get some tips and see his completed kit, which has been very helpful.
Also had a eureka moment reading through the trimming sections of ukswrath build thread, realizing that trimming is primarily get the flat edges to the same width as the cover strips. I kept thinking it was more of a sizing thing, and was stressing over how much to trim (I have thin arms and was worried I would trim things too much, and its harder to add back then take more away).
Hoping to get more time soon to start trimming up and gluing cover strips.
