OP -
You have several issues here.
Front forks, rear forks, moving firewood, hydraulic top-link, SSQA.
Rear forks are handy
Especially if you have heavy loads to move over smooth ground. With no lifting high. I've got rear forks and for moving stuff around they are excellent. As you mention rear lift is greater, about twice that of the front.
My
M4700 is spec'd to be able to lift 2 tons on the rear, one on the front.
Front forks are handy
Especially if you need to push into a pile of stuff and/or lift it high. With my clamp-on pallet forks I can unload a ton on a pallet off the back of my F350, or tear into a brush pile and move it.
A hydraulic top link is a great addition and I yearn for one.
A SSQA is excellent if you have several attachments, say grapple bucket, fork lifts, hay spear, bucket.
From reading your posts it doesn't seem that money is much of a limiting factor so why not get them all?
In my case money is always limiting, so I went with simple rear pallet forks I bought years ago from Agri-Supply for about $150 and a set of front clamp-ons w/stabilizer bar I just got from Palletforks.com for about $240.
And I can swap them between my tractors with ease.
