This one incorporates some triple tonguing. For these moving triplets I used TTK. That seems to get a better flow for me where TKT creates more rhythmic emphatic-ness. Think of slightly crescendo-ing through the triplets. This will keep the air flowing to give your tongue something to bounce off of.
I have trumpet-player-friends who only use TKT and can flow and play “fanfare-ish” using the same articulation. For me it works better to use the TKT for fanfare settings and awkward intervals. Also, I did not do a good job of observing dynamics. Hopefully you will do better!
