and Mr Prince Albert, ironically, my trekking bar bike is a GT also, but a very old one, probably a 90s , a hybrid that was a donor bike that I made into a commuter.

Trekking bars are kinda neat. I really do prefer dropbars for touring and lots of riding time, as a good dropbar setup works the best for me, even for very long trips, but I have to say, trekking bars could be a good option if riding a lot more on loose surfaces, as the wider stance would be nice with a loaded touring bike.

in any case, I do think its worth taking the time and riding with diff variations and being attentive to how diff changes work.
Also, longer rides of an hour or more will also show up slight things that are uncomfortable, so always good to carry tools with you so you can make small small changes and immediately feel if it helps.
