Personally, I just roll my bike up onto my Handy Lift and tie it down to save space in my workshop.
When tied down as you describe, think about how the weight is distributed to the wheels - for the sake of argument lets say it is 50/50.
Some of the rear wheel weight also impact the ISOs as leverage through the swing-arm to the cradle. How much? I dont know. For the sake of argument, lets say 10%.
When on the side stand, less weight would be on the rear ISOs than when on both wheels, as the side stand would be taking part of that weight and transferring it to the frame and thus both the wheels. So, you would see a reduction in the 10%. However, the load would be more on the primary side of the iSOs.
For long term storage I think the best solution has to be on an under-frame type lift with the wheels off the ground. This also protects the tires from the same deformities. And, isnt this how they do cars as well?
