sportsbook review from someone betting small tennis markets and weird props

i've been grinding out small bets on challenger tennis and some super random props, and honestly the limits get slashed real quick even though my volume isn't big. the live lines seem delayed and there's been times the cash out disappears way before the match is even close to done. also noticed some weird rules on dead heats and abandoned matches, hard to find the real t&cs half the time. anybody else trying these obscure markets? do you guys have a book that treats tennis props and small markets fair?
