how much more reliable than irs is a sra? is it harder to tow w/ irs?

 

Less reliable and not as good when towing because you lose ground clearance. Only less reliable because there are more parts to break or go wrong.

It's really more of a rider preference and depends on what type of riding you will be doing with the machine. There are literally dozens of threads about this and I'm sure you will find lots if you do a quick search.
