Here's a classic vid of Sol winning the King of Jester TT. This hill averages 17% and is at almost 20% when Sol comes into frame. His time that day was 2:21, IIRC. My best time on Jester is 2:53.
He's an AWC beast, but he does great in TTs too. Literally attacks as much as RacerEx. You can anticipate either of them being on their own after the first mile.
