That part I agree with. I guess even years ago before taking things more seriously I never really bet lottery ticket parlays. For those, yep, would never touch EG. For smaller players that straight bet, or 2/3 game parlays (or even teasers...they still have +EV priced teasers, granted those will get limited pending results), the bonuses are strong if you can tolerate the sluggishness. That is their saving grace, if there is one. I guess if you assume 97% of players lose, an occasional slower payout isn't a big deal. The better bonuses and low roll might give them a shot at a profit.
I almost deposited for the SB as they had quite a few soft props, but just didn't want to get involved with that again. I haven't played there in a few years (last time was I think 3 years ago, SB props), so I could see the KYC grief and slow pay again. Just wasn't worth it. But, as you build a bankroll, taking advantage of bonuses and some soft spots at shops like these are critical (at least in my experience)
