If you going to switch from pin-on to SSQA it's going to be heavier all the way around.
If you're worried about lift, you will need to find the lightest bucket possible as the SSQA and plate will add 100lbs easily.
Even with any loss of lift it's 100% worth it, I did mine and it's great because I can swap between 4 different buckets, pallet forks, blade, and grapple, I also have a three point adapter that I use to put the landscape rake on the loader.
