About to do first mini-split. Have done split units and always N2 fill and braze.

Approach envisioned for mini-split (410A) is to cut the flare connections off and 15% Ag silphos braze, adding a bidirectional filter dryer and moisture indicator in the process.

Opinions? Is this a wasted effort -- e.g. do mini-split flare connections have a good track record.
Last flare I used on HP (R22) was on a 7.5T carrier HP 30 years ago and was not happy.
