Replying to Bloom Upward vs Slims

So for the past season and a half I have been rocking a pair of medium Upward pants. I have been really happy with them, but I want something a bit longer but not necessarily wider, the width around the legs of the medium Upward looks and feels a bit too roomy for me. I'm a really tall, slender dude, so I was wondering how the large Slims would fit. I want a more fitted, but long so its baggy, type of fit.

I'm 5'11" and 135lbs.
Medium Upward legs look kind of wide on me and I would describe the length as correct meaning that they just barely wrinkle when I don't sag and I have my boots on

I think I remember some discussion about sizing with pictures and height/weight specs but I cant remember where.

That was probably really poorly worded, but I think I got across my main points
