I believe that much of the bounce comes from the tires. The 110 rides just like other construction equipment that I have operated; JD 524 and 544 loaders come to mind. I just slow down when the road or trail is rough, 'cause when you get that harmonic "wave" bounce going; it's not a happy time maintaining control. (If you've ever seen heavy equipment start that bouncing "wave" motion going down the road; you know what I'm talking about.) But I don't seriously believe that loading the tires will change that dynamic.
The hydraulic controls are more responsive and therefore less forgiving of operator miscues. Especially at higher rpms. The FEL and hoe will jerk (very quickly..) and can inadvertantly "smash" things before you can get the word "Sh@#t outta your mouth! So, take your time and keep your rpms down while you're still figuring everything out.
Curly, I can appreciate what you're saying. I think the primary safety concern operating the 110 without the hoe is front to rear stability especially when attempting to use the FEL to move heavy materials. Of course, when the rear end gets light and lifts upward, the machine will begin to tilt off to one side or the other and could roll on it's side.
That said, I would not use the loader without significant rear-mounted ballast, etc.
My HD 20" bucket and thumb are from a JD 27 ZTS mini-excavator. It's a pretty stout configuration - IMO.
If you plan on using chains, you should consider rear wheel spacers. Heavy 3/8" chains will not easily clear the inside of the fenders and will likely rub the inside of the fender.
To genuinely make a fair comparison - is there any chance that your dealer would have a 40x20 machine that he'll let you demo? Even without a hoe, it might be worth your time to work the FEL and experience the ride and control layout, etc.
Best of luck with whatever you decide.
