Yeah, they are quite outspoken. I disagree with them on several points in this episode in particular (and a few in their NHK recap). What I like about them is that they discuss more in depth than other English speaking fs podcasters. Unfortunately there aren't many to choose from – I'm no fan of TSL, to say the least, and IceTalk has become pretty superficial in terms of competition analyses since its recent overhaul. Dylan Moscovitch and Asher Hill are quickly becoming my favourites for their constructive criticism, but they haven't done a recap of JNats yet. I hope they will! I'd be grateful for other recommendations!
Back to F&W – I haven't listened to them enough to judge, if they are generally trying to be objective. I'm sure they have their favourites and bias as we all do. It sounds like they are fans of Utana and Shingo, which I can't fault them for. They are very promising and have the potential to go far in the context of what Japanese id teams have been able to achieve internationally up to this point. For now Utana's (and Shingo's?) ambition to make it to the JGPF next season is a realistic goal and a good way to gain experience, build up the complexity of their programs (I agree with you on their lifts; they don't do a SlLi though – I suppose you mean the curve lift?) and their reputation before turning senior.
The more teams with high ambitions, the better – it will help the entire field to gradually level up.
Sorry for kinda straying off-topic!
