I am looking to get some objective feedback on Ensign. I have done some preliminary homeworks and it looks good. I know they have a 30 day trial, but I want to get some feedback from ET before trying since there is a learning curve over my charting software, Sierra. Ensign seems to offer alot more advanced studies than Sierra for only a few bucks more per month. Is anyone using it with TransAct data? Does it offer historical backfill from TransAct? I seem to have read that they fixed the refresh issue? Is that correct? That seemed to be the biggest complaint on Ensign? What should I beware of coming as a new user for Ensign? Is the support good? I don't like that with Sierra I can only post questions in a forum, no e-mail support. Overall Sierra is a decent value though. Is the user interface easy? I am not looking to write custom studies at all. The advanced studies built in look good, like Pesavantos ( fib geometry and map ) and Pyrapoint. I don't currently use them, but for a few bucks more per month it might be fun to try them out. Thanks for your constructive feedback. Post edit: Is Ensign a multi thread application?
