Guess it depends what you call inexperience, would think of at machine built BSO wheel as inexperience, none of the Fulcrum range are inexpensive, for the distance you have put on the 5, would take it to have been very good value for money.

For Fulcrum wheels, the design has changed over they years, but they do seem to be very reliable wheels, currently I am using a early model 5 for Audax riding, and have no worries about reliability, I did have a Fulcrum 7 that got bent a few years ago, but that took a car driving into me to do it.
