The short answer is, option for CI, no option for a balk.
I appreciate the compliment from PIAA. I equally respect his opinions on many questions here. As he says, many times you can do a search for many of the more common questions. Then if it still isn't clear you can post a sitch. I have found over the years a newer guy will think he has a rule clear in his mind but isn't entirely correct. The only way to know is to post a question or give an answer and find out how you fair with others.
I am 100% in agreement about the importance of the internet and the many clinics that are now available to new guys coming up. I know I wasted quite a few years spining my wheels with no one to help me along. I turned the corner when I joined the local HS group, we train hard. The other thing was finding some of the boards that many of us use. The third was attending pro camps/clinics to get first hand feedback on mechanics. PIAA and I both are local trainers now and spend a fair amount of time teaching newer guys just moving up.
