Yes, listen to Mr Holt. This comes up all the time and THERE IS NO REAL ANSWER. It's about research and selecting your personal options as there are many different opinions. Why not look at what the Todd jacket offers and the G&B since they are based on a film jacket and are usually seen as the most accurate.
As for price and wait times, contacting Wested would be the best tactic to take. As for SA specs, as has been said, there are almost countless opinions. Look over the various options and decide what works best for you.
Thanks for the responses. After doing some research, I think I'm going to go with a Todd's standard. It seems extremely sa, looks great in pictures posted here and is definetely the right price.
Quick question for anyone who owns one; what is the inside pocket like?
