The rear blade FEL combo has worked well for me too. Depending on what I'm doing I use both at the same time, esp if I'm doing my parking area. You can move snow forward and reverse.
I use a 7' Frontier rear blade on a 3720 and a 6' on a 755.
A front blade was nice to have but I found R&R the front blade and its subframe assy just too time consuming when you have a FEL.
I'm considering a 62-66" 3 pt snowblower, just to have it around for big snows. I have a 8hp walk behind that I've had for years that has opened things up when the 755 tractor and blade couldn't.
