Ping has long used a TTL of 255.  Why not do something similar for
traceroute?  To prevent one from seeing 200+ failure lines traceroute
could simply stop upping the ttl whenever the past N TTL settings
failed.  (Eg. if the past 5-10 traceroute TTL's didn't get a reply,
stop incrementing the TTL and exit.)
