Mount for the iPad. What do you recommend, single or dual suction cup? Any additional arm attachments?
Any tips for the training to get through with the least headaches?

Are you an EJet pilot? If so, I'm open to any advice you think important to impart.

Are reserve EJet FOs sitting around, or is there plenty of flying to do?
