Good plan. I had passed on the heater hose attempt and replaced mine with the factory part when trying to control the various oil leaks on the Sport. Frankly, once the breather hose was off, I found it wasn't leaking even after close to 100,000 miles.
It does occur to me that the hose is subject all manner of nastiness from the crankcase ventilation. After all, this is the nasty vapor/ suspended liquid fraction being expelled from the hot oil. Degradation of the breather hose seems mighty dependent on what is in that expectorate. Low grade motor oil, extended change intervals, poor state of tune (especially overly rich), frequent cold start-up, engine wear, and ethanol fuel (and it's nasty binary azeotropes) would all contribute to degradation of the hose material.
