I usually change out something that I know is weak or if I know a better way of doing the task at hand, other than that, I build them per plans, although, I did have a conversation with wendell hostetler one night, I asked him about his skybolt and before he told me anything about it, he mentioned that when he designed it, he over-built the design, and suggested thinning out the stock required. So ther, even the designer is redesigning his own kit, go figure? I just modify what I can to make it my own, the rest I leave as a tribute to the designer.
