What size tip are you using for brazing?

I recently bought a jewelers torch for brazing tube frames and such instead of using my full sizes Victor torch. I was tending to over heat and burning the flux off. I can already tell this little torch is going to be so much better but am wondering what size tip you guys are using. It came with 1-5. Guessing 1 and 2 are too small plus not being able to easily light with a striker. I googled and experimented a little but have zero experience working with stuff this small. Plenty of metal working experience just not used to this tiny stuff. I know I can make it work just for sake of efficiency and ease of use I am wondering what size others are using.

I tend to use the #3 most often when brazing 3/16" stainless or carbon steel tube. It seems right to me, very fine tip and heats the area in no time. I may not have had a good tip when using #4 as it always seemed slower and more difficult to get good flow - but I was probably doing something wrong.

# 3 is what I have settled on also. 4 works just fine too just a little more heat spread but haven’t burnt a joint up sense I got the little thing. Should have bought one a long time ago.
