I purchase the Power sheets from one of the Lotto "Stats" columnist Vince. He is excellent with the 3 digit numbers.
A Power sheet is what he calls his Number sheets. He provides an anlaysis of the numbers. His sheet contains several categories i.e. Cold Position Trap, Power Pair positioning, etc. I ALWAYS hit the number playing his sheets. And although he doesn't guarantee a straight hit, the power sheet always contains a few str8 hits. A sheet lasts for about a month and they are not overwhelming with tons of numbers. I'm surprised nobody here checks out or talks about the Lotto Stats magazine. Stats can only help us. Regardless of that, this guy is my godsend. He also has a website and originated some pretty cool FREE systems like the TRAP SKEET, ICE BOX and Key betting. Number Player dot com in case your interested. Anyhow, the power sheets help me hit, they are worth it for me since I can't hit the broadside of a barn. I bought Aprils sheet; This month I hit 503 boxed, 586 boxed, 519 boxed, 983 boxed -twice, 914 straight, 290 boxed, 642 boxed, and 646 combination. Last month I caught 083 straight, 942 straight - back to back just to mention a few. Like I said, the sheets are broken down by category, so as long as I follow the results I know how to play them.
If anyone wants more info don't hesitate to ask :)
