joBu - yah i do 45deg decline as well, hold the DBs just like you said. i warmup and then do 2 sets of 10 with the 120, go really slow towards the last few to feel a crazy burn. do em monday and thurs. i've gotten those cool side muscles that attach to the abs to come out too from these. and the thing is, my BF isn't even all that low, considering i'm bulking. so heavy really is good stuff... can't wait to see how they look when cut.
I am the opposite of you... I have the top 4 showing really good not even flexed but the lower 2 are very faint... any exercises to hit the lower two??
