Okay....for me....personal opinion here...
I liken the "fun factor" on a 215 vs a 155 to say....a muscle car to a sedan. Yeah you can still have fun in a sedan...but the on demand power at almost the entire rpm range...nah...not even a fair comparison.
I consider the sc maintenance issue an every 2-3 year thing(now...with updated rebuild kit). Just the extra price I'm willing to pay for my fun.
