blade length???

For those of you with snowplows. What size blades are you using? I am tryin to decide which to go with. 54” or 60” A lil concerned about front end squat. Was planning on a 60” at first. But not sure how well the stock front shocks will handle the heavier 60” versus the 54”. This is on the 570 Renegade. Any input would be great. Thanks
