Rollerbrakes ??
do any of y'all have opinions/experience with Shimano's roller brake. it was suggested by one of my favorite bike guys, he insists they are superior to discs which I don't believe for a second but I'm thinking about giving one a try. at the Drs yesterday I weighed in at 349 pounds so I buy into the "heating up on descents" theory more than a lighter rider... thoughts ?

I just read through some of this. https://www.sheldonbrown.com/rollerbrakes.html
I'd pass based on this,"There have been reports of grease's catching on fire during long descents!"

Rollers are even less influenced by weather than discs. Will go longer before needing any wear items replaced.
Won't give as much braking for a given amount of hand effort.

the weather part I buy and think it's a really good thing but at my size I want something that works when I ask it to

When I was touring Europe my system weight was 330lbs and I did 80km/h mountain descents just fine with discs. I had a 203mm front disc and I managed to burn up my brakes a couple of times, but that just resulted in slighly less power for a couple of km's and more noise during that time.

Roller brakes have been known to overheat - although I believe the Shimano ones with the big cooling discs are supposed to do quite well wrt this - but are generally supposed to be quite reliable.
I wouldn't worry about instant failure. Possibly gradual fade.

Well, how long are your descents?

I have used rollerbrakes, and yes, they began to smoke on al long descent. So don't use rollerbrakes unless you are cycling in a very flat area. In fact the combination of 21+ gears and rollerbrakes is downright dangerous, suggesting that such a bike is capable of climbing hills. It is, but the descent will be very dangerous.
