Yes I try to get the firing order right but I don't stress out if I have to relocate a wire to make it fit.To me it is all about having fun .Now if you are building for a contest ,that is a whole different kettle of fish!The contest model must be built to the highest standards you are capable in all respects to have a chance at a prize.The building process would be longer and frankly not as much fun and it becomes a chore.Not for me!I require no external validation for my builds and a trophy represents some others person's evalyuation of my work,something I neither want nor need!Call me kooky but iIjust want to have fun builfding models of all types!
