Mine was matched to the 66" in Apr this year. Dealer discussed upfront and itemized it on the contract (it was an option FWIW). I questioned everything and they were very good. Also, Group here on OTT had great advice on a lot of stuff.
So... here's the trade-off: You have a certain amount of lift (x - don't remember exactly) at the pins and less moving it out. The question is what are you mainly planning on using it for? Your bucket is heavier and can fit more. Max Lift Lbs is determined by the hydraulic pump as I understand it (Same on L 25/33/39)
Lighter bulk material like clean-out of the barn, mulch, etc would be perfect. If you are moving soil/gravel/rock/even sand you skew the ratio and also have to think about ballast in the rear - YRMV.
I have woods and find the 66" well-matched size & maneuverability wise. But I am mainly moving dirt/rock in combo with my BH.
IF you are OK with the size, the solution may be just don't as big of a bite if you have dense heavy material and encounter issues? You just got it so double check your contract, think about and call them for options. IMO I wouldn't give up yours until the replacement is in-hand if you do decide to change
but you've been sharing with us in recent years down here in PA!
