The one worry with single cone techniques is the possibility of faster sealer wash-out if coronal leakage occurs.

My primary technique is vertical condensation with a non-standard cone. I use lateral with a warm vertical down pack in larger canals in order to control the gutta percha in the apical area better.

For both techniques I backfill with Obtura.

as for the brasseler files, i have a seperated file in the MB canal of my own RCT-ed #46. the file was small enough and the dentist was able to push it to the side and continue instrumenting and the tooth hasn’t bothered me since. but i had one separate on me when i was practicing in new york, had to refer that case out because it broke right at the middle third.

however, i do like the concept of the brasseler endo-EZ system, with the single cone obturation corresponding to the last file used. that new york office didn’t have an obtura machine and i was trained doing lateral, and i found that my fills were very dense and three dimensional, very easy to use. now i use obtura (which i’m still trying to master) and thermafill. what do you use and how do you feel about “single cone obturation”?

The risk to instrumenting larger is, of course, severe apical canal transportation.
