I am a 2 panel ROS mini-John Eberhart...well maybe not a real mini John but I did watch a lot of his videos when first deciding on which saddle to purchase. Anyway, I have used a ring of steps with a ratchet strap for the past 2 seasons. 99.999% of the time I tried a Tether platform that I purchased when I bought my son and son-in-law each a saddle and platforms. They both love their platforms but I will not be using the platform again.
I do all day sits 50% of the time and I love my ROSs, I wear Muck boots with no foot pain at all. I like the security I get with the ratchet straps for my ROS but it is cumbersome to say the least.
Disclaimer... this is the only way I have hunted so far and I may just be ignorant to the advantages of a platform and to stupid to realize I am not comfortable.
Heck it is only money, try them both.
