Switching to longer blades?

Has anyone tried running blades that are a bit longer than the standard/recommended blade length for a particular model? On my Rogue 72" I've always battled two 'mohawks' of grass at the point between the three blades. It's not awful, as in completely uncut strips, but it is pretty noticeable everywhere as being two slight strips that aren't as flat as everywhere else. I was thinking of trying some blades that are just a bit longer than the stock "24 inch" blades to get a bit of overlap. Of course I'd ensure that the clocking of the blades is such that they never meet and touch each other. I haven't actually looked to see what other lengths are available, so maybe this idea is bunk if there are no ~25" blades out there...

I'm unsure why my Rogue behaves like this. It has occurred with both the stock blades and Gator G6 blades. I can't believe it is some type of adjustment and I know for a fact this occurs when my blades are freshly sharpened.

This problem sounds like the wrong blades are repeatedly being used. The three blade decks have the middle spindle placed forward of the 2 out spindles on purpose to prevent "mohawking".

Putting incorrect blades that are too long, they will hit the deck housing.

I have had this issue once because I got blades from a local hardware vendor because the guys were just picking out blades based on measured length of the well-worn old ones.

Use OEM blades or equivalent aftermarket blades. With that 72" deck, run it level all around. No forward pitch.

Unless the blades are gear drive or clocked with a timing belt the blades will not stay clocked and will collide
