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!
