I will shed my limited experience here from my own experience of Cassidy SBS setup. They are probably the best SBS setup I have tried (I tried Statstuff & ADM). quality, look & feel are much better than the rest i have tried. Starstuff side by side had one feature which i really liked where I could slide the scope individually horizontally. This feature is probably just unique to Starstuff set up.
All SBS needs perfect balance. if not balanced properly you will get drift which will give the impression of flex. If you have perm setup than you only need to do it once but if you are like me with out a perm setup than you need to do it everytime you setup. You don want to slightly miss balance and later find that star is drifting in main slightly between exposure to exposure.
I found SBS harder to balance compared to mount on top. but once balanced it gave me better result compared to mounting on Top (less pron to wind, need lesser counter weight)
i never use SBS with my lighter setup, because weight of SBS will overweight any additional gain (eg imaging with ED80 & ST80!)
I do use SBS when i use my hevier setup of 10" reflector with ED80.
