Hi Leo
I hope you have had chance to read some of the links (I have to admit there is so much to read that I haven't had time to read all)
I think it's not a matter of tradition versus modern in the haiku form (well, I think all traditional crafts are better made than most modern) but more a translation of syllables, when English syllables don't match up to Japanese -- but then I'm sure you'll have read that in the links by now.
Happy learning & I look froward to your writing
