BR6800 vs BR8000 Calipers - Worth the Upgrade?

I want some "good as it can be" rim braking on a couple of titanium bikes that look great with black accessories. I'm considering two choices:

1) New BR8000's @$220 CAD. I've read some stellar reviews on the braking power of these things.

2) Some used BR6800's @$120 CAD. Not so many stellar reviews but structurally similar.

My criteria for choosing is:

A) If the BR8000 would provide even 15% more braking power, that would be my choice.

B) If the BR8000 were "blacker", that might swing my decision in the event of a near tie. I find it difficult to tell from pictures online which units are truly black versus dark grey.

Does anyone have knowledge of both calipers such that they might comment on relative braking power and "blackness".


6800

8000

The 8000s have sections of true glossy black and sections of a flat black that maybe appear "less black." 8000 are rated for 28mm tires vs 25mm for the 6800. The 9000 with the metallic juxtaposed with the black would be the best looking choice for a Ti frame, IMO.

Ah.. the 28/25 is probably why these things are coming available for cheap. One of my bikes maxes at 25 but I'd want 28 for the other. The 9000's do look great but, for me, not quite 2X cost great vs the Ultegras.

I think the 105/7000 are a true glossy black, will clear 28mm and probably work as well as the others.

I would be all over the 105's if they do, in fact, work as well as the others. I can get a set of those for $120 shipped. I can't find them now but I stumbled across a couple of Ultegra reviews that showered those brakes with praise for their stiffness owing to some cross bar piece or something. I'm not sure if that same technology has trickled down to the 105's as I would hope.

With KoolStop or the best Shimano pads, I doubt anyone could tell the difference in how they work. I had nice 7800 brakes on my Lynskey, switched to an 8000 group and had a fair amount of trouble getting the rear 8000 to stop squealing. I couldn't tell that they worked any better than the 7800 even after I got them sorted. Or the 6600 that came before, for that matter.

Whatever calipers you choose, make sure to use compressionless housing for even more power and responsiveness—not to mention lighter weight.

As shelbyfv said; KoolStop Salmon pads can make a large difference in feel, modulation and stopping power of most any brake. They’re relatively inexpensive, fit the Shimano pad holders perfectly and won’t score your rims. I’ve used them on all of my bikes for many years. They are the best pads for aluminum rims in the wet.

Seriously?? 6600 is actually what I'm replacing on one of the bikes and I was really hoping to improve upon that.

Thanks, all for the tips on the koolstops and the compressionless housing. Sadly, I recently invested in a giant spool of quality housing that is not compressionless.

I have 105 7000 calipers on my Soma Smoothie. The braking is excellent with the stock pads. I am a fan of Kool Stop orange pads, but will wait until I wear out the stock pads, they work that well. I have used these brakes on numerous different rims, with 25mm to 32mm tires. I have 6600 calipers on a different bike, IME, the 7000 are much better. The 6600,IMO, are not so good, and definitely benefit from going to the Kool Stop orange pads, and, compression less housing can help, I am using the 7000 calipers with the regular housing that comes with Shimano brake cable sets, along with the stock pads. The entire 105, 7000 group set is very good.

Thanks delbiker1. That's just the kind of data point feedback that I'm looking for.
