On my visit last week, the line for Crush's Coaster was 70 minutes shortly after park opening, and stayed that way until late afternoon, when it dropped to about 50 minutes. Long line, but I really felt it was worth the wait for a first-time ride.
While I wish there was a fastpass option, I can understand not having one. On the similar-loading speed Mulholland Madness at DCA and Primevil Whirl at DAK, the use of fastpass makes the standby line crawl to the point of annoyance (except when PW is running both sides, in which case there is sufficient capacity). The line at Crush's Coaster already moves slowly enough without fastpass.
I happen to think that Crush's Coaster could benefit significantly from the type of advance queueing system that was tested at RnRC a few months ago and will be installed at Dumbo in the FLE expansion. It isn't fastpass, but it allows you to move around and do some things without losing your place in line.
