Jumping in here because I went through a bunch of these when I lived in the city. I spent way too much time obsessing over the perfect setup for my rangefinder. Honestly, the rope straps feel great once they soften up, but the length is always a gamble. I ended up trying a few different styles because I hated how the standard thin ones dug into my neck after four hours of walking.

• Rock n Roll Straps M-Type Napa Leather 100cm
• This one is cool because the design actually stretches a bit. It is like a shock absorber for your shoulder. It looks distinctive but not flashy.
• Gordy's Camera Straps Horizontal Lug Mount Leather Strap
• Much more low-key. It is basically just thick leather and some waxed cord. It starts out feeling like a piece of cardboard tho, so you really have to work it with your hands to get it supple. Both are way under that $160 mark and dont have plastic bits to worry about. The leather on the Gordys is super tough, like it will outlive the camera tbh. The Rock n Roll one is better if you want immediate comfort without the break-in period. Just make sure to get the right length since you mentioned being shorter... I usually go for 100cm so it sits right at my hip.

Congrats on the M10! I've been super happy with mine and totally get the stress of picking a strap that wont ruin that finish. Before I suggest the absolute best fit, are you planning to wear it cross-body or just around your neck? Chicago street shooting means you'll be moving a lot so the hang height really matters for comfort. ngl, the scratch thing is a legit worry. I avoid those plastic clips because the rubbing is a real reliability concern for me long-term. I prefer a simple leather lug setup because it’s basically fail-proof. I’ve been using a braided leather option and it's the most satisfied I've been. It’s flexible right out of the box and doesn't scream expensive camera at all. TL;DR: Get a braided leather strap with integrated bumpers. It's low-profile for street work and protects the lugs from scratches. I'd look at the Barton 1972 Braided Leather Camera Strap or the Gordy's Camera Straps Leather Neck Strap with O-ring Protectors. Both are well under your $100 limit and super secure.

Seconded!

I went through this exact same crisis when I got my first M. tbh I started with the Peak Design Slide Lite Black because the quick connects seemed like a no-brainer. After a month though, those plastic anchors started leaving little buff marks on the finish of my top plate. It killed me. Switching to a Street Strap Silk Rope 42-inch was the best move. It is way more comfortable for a full day of shooting in the city. The silk just slides across your neck without that friction you get from leather. Since you are worried about height, definitely look for a shorter length like that 42-inch. Some leather options like the Tap and Dye Legacy Leather 40-inch are great but the break-in period is a pain... the rope is soft right out of the box. Just make sure you have those leather protective flaps by the rings so you dont scratch the lugs.
