I bought the 32” version first, since I was doing almost exclusively big stuff (> 30” diameter) for several years.

Later, I added the small pair, since the big pair really doesn’t hold on well to anything under maybe 14” diameter:

To be honest, I’ve been favoring a choker more recently, for dragging logs onto the trailer with the winch. My choker is a 10 foot length of 5/16” chain with a slip hook on one end and a grab hook on the other. It’s often a PITA to get this around a log that’s on the ground, but I find that the tongs can be tricky to set on some trees when working alone. I was even thinking of changing the slip hook on my winch cable to a 5/16” grab hook, but the problem is that I would need to find a 5/16” grab hook with a 3/8” pintel, as that’s what you’d need to get it onto a 5/16” winch cable with re-I forced eyelet.
Do note that a winch set up with 5/16” cable (eg. 7500 lb.) can easily break 5/16” chain, I should really be using 3/8” chain to be “legal”. But I’m already heavily invested in 5/16” chain components, and I haven’t had issues, as I’m only dragging logs. The grab hooks on both sets of tongs are also 3/8”, though... so maybe I should bite the bullet, and just upgrade everything to 3/8”. That’s a lot of weight, and a lot of money, for the amount of chain I carry with me.
I still prefer the tongs for dragging trees off the trailer with my front-end loader, though. I can often grab a log and drag it off, without even having to get off the tractor to set them, if the log diameter is in the sweet spot of the tongs I’m using.
