Yankee, you forgot to tell us how high you're gripping. Also, it would have been a bit easier for us if you sorted your candidate poles in order of length and weight. This is the sorted order:
10-6 140
11-0 140
11-6 130
12-0 165
12-4 140 13-0 150
13-6 150
14-0 140
14-0 145
I've bolded the pole that you're losing (in the list above), and greyed it out (in the chart below). Here's the relative flex #s of your candidate poles (highlighted in yellow).

You didn't say how much you're bending the 12-4 140 now, but no matter what pole you decide to use, it's going to bend a little more or a little less than what you're used to. With a PR of 10-6, I'm going to assume that you're not bending it much yet, so you're not too fussy.
Please let us know your grip and how much you're bending the pole (or how much you
want to bend your new pole). The less bend you have now, the easier it will be to transition to a new pole.
In the chart above, the leftmost column shows the relative flex #.
So depending on your grip, you'd probably want to use the 11-6 130 (for more bend), or the 12-0 165 (for less bend).
I doubt that you're gripping on the last 4 inches of the 12-4 140, so the 13-0 150 is probably too long for you (and too heavy).
Likewise, the 10-6 140 will be too light for you (and probably too short).
If the 11-0 140 isn't too short for you, you could use that instead of the 11-6 130. They will have about the same flex.
