Still Learning
I finished my chase at Bowmans this past weekend. It was quite an oddysey by the end. I actually lost money through some bad luck and bad choices, but I learned so much from this chase that I do not consider it money wasted. Sort of like paying tuition. 
In fact, I learned so much I am planning to write a permanent article for the website. A "Here's how to piss away a $500 bonus" don't-do-this type guide. I want to give a recounting of each bet, and why I did what I did, and why that was the right or wrong thing to do in that situation. I'll tell you flat out I am a little embarassed at some of the positions I put myself in - as I am supposed to be the expert, but I think the readers here and members at BullsBetting (a remarkably overlapping crowd!) respect my candor, so I am going to lay it all out.
Bottom line on the chase: I deposited $3350 for a $500 15% bonus, incurring a $15,400 wagering requirement. I finished with $15,822 in my Bowmans account. I became very concerned at one point that I was going to get stuck - run out of bankroll before I ran out of wagering requirements. That part is not my fault - I just had a seriously distressing string of prevailing underdogs.
Bowmans allowed me to withdraw all my money over 2 days. They were weird about it, though. I couldn't request more than $2,500 at a time. The first day I requested $2,500 and then submitted a second request for $2,500 and got a message stating I could only request another $1,000. So I did. After that I could not request any additional payouts. The next day (Monday) I requested another $2,500 and got a message stating I could not withdraw any more. I contacted CS and asked why, and the CS guy apologized and "reset" my account and I was able to withdraw the remainder of my cash in $2,500 increments. There were no fees for cashing out. The first $3,500 hit in just a few hours. I expect to be paid in full by Bowmans by the time I get home this evening to check. (I am typing this from work, and I don't want to check Neteller from work.)
Bowmans is burned for me, so I plan to move to another book. Most likely Las Palmas, as I was checking them out last night.
