I don't have a transpac but an oceanic chute 3 which is a wing type bcd.
I've really liked it for a long time and it's true that especially with heavy coldwater gear it can have a stabilizing effect.
However this stabilizing is starting to annoy me a bit when it comes to tropical diving. I like to be able to dive in different positions and the wing tends to force me into an either horizontal or vertical position depending on how much air I put into it.
Theres lots of things you can do fooling around with weight placement but in my experience solving an issue of too much air in a specific place by piling lead on top just causes other problems.
I find that my buoyancy is near perfect when it's empty and I keep it so down to around 25 m anyway.
But I'm considering trying out some traditional bcds to see if they allow more freedom of movement when diving light.
