My "5 Commandments" as an enthusiastic PCP lover: 1: Never be a "fanboy." 2: Always be strict but fair in your assessments. 3: Don't be influenced by sponsored reviews. 4: Never pass on "hearsay" and then proclaim it as "truth." 5: If you don't have any technical knowledge, don't engage in discussions.
After some tuning, it's even more enjoyable to enjoy our beautiful and fascinating hobby!
