Your story reminds me of my return to trad in 89 and my first arrow purchase. I bought my first recurve, referred to the Easton arrow chart and bought the recommended 2219 shafts for my 50#@26" bow. Of course they came out of the bow sideways. It took me a long time to find anyone who would take these tree trunks off my hands for free.
I will always speak up when I see someone being steered in the wrong direction on traditional choices. If questioned by the person with the bad information I will say" I have made 138 longbows, won the state selfbow championship twice, helped run a city owned, public indoor range for 15 years and spent Tuesday and Thursday evenings at the range tuning bows and bare shafting arrows for people free of charge", end of discussion.
One local pro shop has my phone number and has guys with trad questions give me a call.
