Maybe not the safest sportsbook compared to Pinnacly, Olympic, Betwwts, Cris, but it is safe. Especially since Madjack has it listed. He will back you up in case there is a problem and you have a legit case.
I just deposited $3,000 there and received a 20% CASH bonus. I only have to roll it over 3x. That is a great deal. $600 free cash. Can't beat that. Although they limit me to $500 online wagers, but you can call in and bet higher if you wish. I think I even got a free VEGAS INSIDER subscription but I don't really care about that.
Customer service was excellent. Andy handled my account. The site doesn't really advertise 20% bonus but they will give it to you. If you have problem getting it, ask for Andy.
If you want a 20% bonus at one of the safest sportsbooks out there, go with betwwts. I also deposited there $5000 and took advantage of the 20% bonus. I picked up $1000 cash free. Although you have to roll it over 5x. The only thing about betwwts is I usually can find better lines at other shops. So why did I deposit there? The 20% bonus and it is rock solid book. If it takes me long time to roll it over I am not worried. I know my money is safe. I'll only play there when I can't get a better line at another book.
Right now I would go with those 2. Both offer 20%. One you have to roll over 2x more but have more safety the other only 3x and it is a safe book. More importantly, it is 20% CASH bonus. Don't get fooled into match play.
Maybe splitting up your money with 2 books is best option. Then you can shop for the best lines. Could be the difference in winning 1-5 more bets this year! Or pushing. Especially if you like playing 2h lines.
Thats my 2cents. Good luck whichever sportsbook you choose (if you haven't chosen one already). You are smart looking to take advantage of the bonuses. I do too!
One more thing. Pinnacle is the #1 sportsbook IMO but not good for bonuses. Although you get a 10% bonus and I think it is only 3x roll over. Could be wrong. But def. #1 in my book.
