Changing our spiel is fraught with danger (8)
I believe the answer is:
perilous
'fraught with danger' is the definition.
(I've seen this in another clue)
'changing our spiel' is the wordplay.
'changing' is an anagram indicator.
'our'+'spiel'='ourspiel'
'ourspiel' anagrammed gives 'PERILOUS'.
'is' is the link.
(Other definitions for perilous that I've seen before include "Hazardous, menacing" , "Hazardous, dangerous" , "Full of danger" , "Risky" , "promising danger" .)
