Looking for insights from long-time BPO peeps

Hi all.  I have been reading your posts with great interest as I have been nibbling on BPO.PR.A and N, and now am doing a deep dive to justify bigger bites and perhaps other series.

Might any of you have some insights on these Qs -- or anything else that comes to mind?:

1. Why do the C, E, G, and I series with minimum coupons trade at such a high premium to those without when the value of the floor is overtaken by the value of the par fixed spread on current price?  Those series will have higher dividends only if GoC 5 goes very low very soon, which seems unlikely. A minimum coupon is great if the issuer is blue chip, but for a distressed issuer, why not buy the cheapest series and not ones with theoretical value way down the road? Why are hedgies not shorting these against the cheaper ones?
2. More broadly, aren't these significant price differences a great indication that the "market" does not foresee a problem with the dividends? Someone posted about the BPY US prefs trading much higher and how puzzling the price difference is given that BPY prefs = BPO prefs in a liquidation.  Am I missing something?
3. Why do the Ts trade so much higher than the other series that also don't have floors?  Is it because buyers focus on current yield and ignore (or are ignorant of) the coming resets?  Series A in particular, resetting in Dec, seems a much better buy.  If the anser 
4. Is there a way to gain insight on NCIB buying before the monthly report (and does anyone get this pay-walled info)?  Is there a broker known to run the buybacks for BPO?  I've been watching series W X Y since they are so so illiquid and they have a 1000 share daily buyback cap, but can't see a pattern so far.  I see from the NCIB application that public float is less than issued, so does that mean that BPO has previously bought back these shares?
5. Have you seen any significant price moves around ex-div dates?  It seems to me shorts would rather not write those cheques unless absolutely necessary.

Thanks so much!  My children will be pleased if my greed for 20% dividends is justified so they can fly first class.
