this may sound weird but i've finally developed a sense of balance in terms of what i call apollon.
for context, i feel weird if i say apollon all the time because it feels too formal and restrictive, but it feels too casual to constantly say apollo too.
so now, instead, when i'm talking to or about him in a lighthearted / casual manner with other hellenic pagans or other devotees ( or just yapping to him about my day ), i say apollo. when i'm talking to him formally ( i.e, inviting him for a reading, giving a formal prayer, etc ), talking about him seriously, or talking to non-pagans about him then i say apollon.
this is a weird analogy but it's kind of like how in some fiction, the king's son will call him father or dad in private but address him as "his majesty" or "your majesty" in front of others!
point of this post? i don't know, kind of a reminder that your practice is your own, and that you can mix and match if that works for you.
