If your willing to make the drive for 250, you might as well still come for 198. Quality is about the same. My cutoff for Numbers is 125, then I just run Fractions. We do that as low as it goes, which was about 60 cfs in 2012. Didn't have to portage, didn't get beached.
I wouldn't put in at Stealth though. #0 isn't worth the flat, shallow water between the Numbers launch and #1. Park at the green gate just before the AHRA pay station (but don't block it) and walk down the old road about 100 yards to the top of #1. I would just go to 5.5, but everything still goes all the way to Miner's Camp or Railroad Bridge.
