I have a pile of various track stands. The problem with the old school ones is that they do not work with a REV GEN 4/5 with the big upsweep on the bumper. Many of the current ones on the market push in hard on the snowflap.
The best I have found is the Easy Move Snowmobile Warm-Up Race Stand with Lift Handle. The "race" version has the wrap around aluminum side protectors, which you maybe do not need, but it seems to stiffen and strengthen the stand. The lift handle versions use leverage and make lifting easier. The hooks, however, are too small for most bumpers, so I use a short double loop soft strap / sling and wrap it around the bumper.
They are not cheap, but they are always at Hay Days and some other fall shows and have discounts and like dealing with Benjamin Franklin.
I have several of the Raider and other Chinesium Amazon knock-offs. Some will not lift high enough or they break and I have had to weld and repair and/or modify and reinforce several of my non-Easy Move stands.
