I see that for your first few weeks, you were using steadily increasing weights with each set (unless I misread the info). How do you feel about doing the opposite - starting out at maximal weight and doing less weight each set until you reach the least amount of weight you can stack (I forgot the name of this method - "negatives"?)
I've always found it a really good way to press muscle failure. After your first 5 sets or so, the lighter weights are much harder than the harder weights you started with (since your muscles are so depleted, etc). Really good way to sap every last ounce of strength you're capable of.
