The step down in power does not affect the taper which is where the blank of the rod bends. I use an old st croix avid x 7ft med/fast exclusively for spooks, traps, mid-divers (dt6), and squarebills (+/-1/2oz), combined with a 10-12lb mono or co-polymer line I have an exceptional hookup/landing ratio. I used to use a dobyns 705cb (7ft mh/mod-fast) for the exact same applications. While the med/fast may technically give up a little power it's barely noticeable in use, but what I feel I gained was better hookset power which is what I attribute to my high hookup/landing ratio. The x-factor here is that different rod companies can vary a bit on their power and taper ratings.
