Hey guys! Starting to think about a road bike build and I'd like to use columbus max top and down tubes. I'm curious about the ride quality and think working with the shaped tubes could be a fun challenge. After some research I see that the new Max tubes are niobium, which like the thread below will be my first entry into high end tubing. I wanted to ask if folks here have some pointers for fillet brazing the stuff. I'm guessing fillet-pro might be a good route, assuming it's more heat sensitive than the 4130 and ZONA I've used before. That said, it's also relatively thick walled for niobium tubing, and I feel more comfortable getting a fillet down quickly in brass. Appreciate any insight!

Best
Chris
