A simulrec is a great idea. We used them all the time at the BBC World Service. Two people talk to each other via Skype or the phone. While talking via Skype/phone, both of you also record the conversation into a high-quality microphone. So, you chat through the phone/Skype, etc.; however, both of you also record into good mics at the same time. Once the interview is over, one of you sends the other person the high-quality audio WAV/AIFF file. The other person edits both quality files together. Now, you have an interview where both people have high-quality audio, and it's not crappy audio recorded through a PC microphone.
Everything you say needs to have a beginning, middle and end. And I mean EVERYTHING! In the last 18 years, I've seen soOoOOoOoOO many presenters waffle and waffle. They think they're amazing by just 'giving it;', when in fact they're just talking cow poo. And trust me, I've heard sooooo much cow poo over the last 18 years.
Before you open your gob, know EXACTLY what you're going to say. Know how you're going to start your presenter link and MORE IMPORTANTLY know how you're going to finish it.
Ask yourself this: how are you going to introduce your next item?
Random waffle is baaaad; prepared speech is awesome.
So, do you know what you're going to say now?
