Plodding Along
I popped $300 into Players Superbook for a $60 bonus on Tuesday. They run pretty much non-stop at 20% bonuses via Neteller, 4X rollover, but they have a 30-day wait before you can withdraw policy. That's a hassle, but I figure over time I should bust on the first bet 50% of the time, so it averages out, and makes it worthwhile. Unfortunately, I didn't bust on bet one this time. I couldn't find any decent lines for Wednesday's games, but I have it all in on two games for today. Maybe I'll get lucky.
I received SHARP SPORTSBETTING by Harry Wong from Amazon yesterday. Looking forward to reading that - it is the most highly recommended book I see in SportsBetting Forums.
I realized recently that my self-imposed rule of having at least the rollover requirement for the book you are currently chasing in reserve at another book is not excessively conservative at all - as I had first thought. I think if I illustrate with an example it will be more clear as to why.
I deposit $200 into Book A for 20% at 4X rollover. I have $240, and my rollover is $960, so I have $960 in Book B as my reserve to bet against Book A. First bet, I take a moneyline for +200 at Book A, and -200 at Book B (I'll take an even up wager for the opportunity to bust in one bet.)
I put $240 on Book A (+200), to win $480. I must put $480 on Book B(-200) to win $240 to offset. I win my bet at Book A. Now I have $720 in Book A, with a $720 WR remaining. I only have $480 left in Book B to bet against it. I may end up getting my whole BR in Book A, and not have any money left to bet against it in Book B, even though I had the entire rollover in reserve when I started. It seems very obvious when I write it all out, but it did not occur to me before. Perhaps I am slow, but at least I can learn. 
Moral of the story: YOU CAN NEVER HAVE TOO MUCH MONEY TO SCALP SPORTSBOOKS FOR BONUSES. I don't think I am going to adjust my criteria at this time - having 1X the rollover in reserve - but I will be more wary where I stand than before, now that I have figured this out.
