Six Mile soon

I’m looking to run six mile soon-1st canyon; second canyon, possibly.
Its been running about 600 cfs
I’ve done it in a big raft at higher water-but not in a baby raft.
I’m doing it Soon, solo if I gotta.
Any experienced boaters wanna go?
If I haven’t boated with you before I wouldn’t mind doing a warm up run first (guardrail, if it rains. or?)
