Hmmm....advantage???...more a "style" and "modality" than anything...If your system works...KEEP IT!!!

I "template" all my joinery...so technically only lay a joint once in full scale "joint maps" that I used to draft out now I print them out directly from my blueprint "layout" CAD modeling...So these have "targets" (points from the story pole) on them and these get placed on the "line layout." This is actually a very ancient system, just with modern tools, inks, and related materials...I like the ink because it is a traditional system of layout...I seldom need to plan it off do to error in layout because of the "story poles" I use...Ink shows up much better...is more durable. I use pencil too...but it is a soft dark lead .7mm and/or .5mm for some applications...
