Not saying it's wrong - but I find hill climbing easier on the drops - but I do get out of puff - but less so than sitting up
As per my post slightly before yours, and probably crossed during posting, whatever works for me may not work for you. A very small proportion of people can efficiently climb in the drops compared to other methods, but if you're good at it then stick with it.
I might actually give it a try on next ride out to compare to my usual position. Although my new bike is a lot more aggressive in its geometry and has 2 spacers above the stem by default, so am in process of deciding where I want the stem set, and therefore might find it not great at present. Definitely worth a go though.
I am persevering with the height, as it's a great position to be if I can handle it. My bike got guy has offered to tailor it as often as I like when getting the bike run in.
