I've never ridden a Deere but I'd guess that most center engine sleds have similar problems. The worst I've found is how the weight comes off the skis when you're under power so you have to come off throttle to turn...
The '71-'73 TNTs are very similar (the '73 had a cosmetic refresh but was basically the same sled) and were known for poor handling.
