ORDERING CUSTOM RODS Vs FACTORY RODS - Measurements I'm trying to understand the basics of how placements of custom rod components laid out by experts during a 'fitting' typically differ from factory rods. I am mostly interested in saltwater rods used in San Diego fleet like a 196 blank to XXH (with non-roller guides because laying them out complicates my question). BUYING A USED CUSTOM SALTWATER FISHING ROD It seems a buyer should be careful and be aware of how custom rods can differ from factory rods if he is buying used professionally-built custom rod because a custom fishing pole was most likely tailored to the person who purchased the rod - correct? My instinct is that determining the correct position for the REEL SEAT is the most critical first move - correct? I reason this because the 1st guide (closest to the reel) will start the sequence (spacing of guides) to the tip, and those don't change much and can be found on manufacturer's guide charts - correct? When I built my rods some 20 years ago, before youtube and the internet were as populated with info, I based my placements on measuring factory rods, but I'm about to start on a new calstar XH blank so I am trying to improve my layout a little (or at least keep it generic to factory specs). ROD BUILDING CLASSES: I've noted in reading this forum there are rod-building seminars and classes available, but I don't have time for that and I'm hoping someone can shed some light on my questions without recommending me to classes. Meanwhile I will continue looking for useful online tutorials and videos that don't get too deep or broad.
