Got a new Avid-X last week for spinnerbaits, a MH/F 6'6".  I was actually using a M/XF rod just because that was my extra rod, needed some more backbone I thought.   Broke it in the night I bought it with a couple of 1.5#'s in my backyard pond, but yesterday I got into something that made me glad I had the extra backbone.   Close enough to 4 to call it 4:

I own the same rod, mainly because it was marked all the way down to $80 at Scheel's. Didn't need it, but couldn't pass up on it for that price. 

$80 - wow.   I like the rod so far.  I'm actually really getting used to and even liking the split grips.   I caught a huge bluegill the other night in my backyard pond on it - with a buzzbait.   That was fun.
