I got the blue in the 50r spec. I've been running nearly flat bars most of my life but over the last few years have transitioned more to all mountain/downhill riding and these have completely changed the way the bike feels particularly on steep descents the riding position overall makes you feel much more confident and in control (where as flat bars on steep descents can give you more of a feeling of going over the bars not to mention the general riding position is more comfortable. Feels more similar to riding a dirt bike. The steering does feel more vague on flat trails and turns with a hint more understeer feel. Climbs have your arms just a bit more tucked towards your chest but I'd say the benefits I get from it otherwise overshadow these cons.
The quality of the bars seems good. I trimmed them down to 780 and found the measurement marks on my bars to be fairly close. One side was spot on and the other side was off by about 1mm. Like any bars if your going to trim them it is best to use a measuring device to get the most accurate measurements. They cut pretty clean with a pipe cutter. Although I wouldn't necessarily recommend it I was able to drill and debur two small holes in the bars to route cables for my ebike controls. I have around two dozen hard rides on them so far and they have held up well. The bar ends also work well with the Granite stash in-bar tools. The color is a very rich vibrant blue and seems to match most aftermarket anodized blue parts colors pretty well.
If you are debating about which meauremnt to go I'd say if you ride primarily cross country go with the flatter bars and if you do a mixtures of steep stuff and cross country somewhere in the middle. But if you ride mostly downhill stuff like myself then go for the higher r.;
