In general you should be okay in mild winds.
You could consider changing the front REV rods to the "Revolution Equipped"(4 wrap). That includes the SLE rods in RE. These are normally the rods on the REV 1.5 vented, not the JB. No need to special order tougher rods on a fiver.
As I was training my REVs together before REV ever sold the them as trains, I developed several ways to do the trains. The pig tails method is what I use the most. As I have used this method for over 10 years, I am not sure whether I developed it or maybe saw the idea on Sam Riiter's trains. I don't even remember anymore how he connected his REV trains together.
The attached picture should explain how I do my train lines.
JM, with respect to the pigtail attachment, are they simply larksed onto the end caps or a hybrid larkshead/half hitch? Looking at the photo close up looks a bit different from just a larkshead.
