How desperate and knowledge hungry are you? Shit, it must be worth something. Probably not the revolution of twin-tip skills, otherwise we probably would have known it existed already. But if you're really interested, I would surely get it. Hell, I have bought most of the instructional videos I could find when I could scrounge up the dough, and if they provide even mediocre insight, I consider them a worthy investment.
Freeze has some nice tips each month. Freeze is definitely the Powder of the park world. A lot of their tips are pretty advanced though: "540 onto a rail," "backflipping a hip jump", etc. There is usually an issue each year with tips and tricks for all skill levels though with a few pro's. I have my issue from last year I could send you if you want me to copy the pages and mail them to you. PM me for details.
Like I said, it's all in how desperate for knowledge you are.
Stoke on man. I'm a gaper in the park (and these guys will tell you that's a SEVERE understatement), but it's surely a hell of a lot of fun trying to get better at it. Good luck. 
Edit: since you mentioned that you have already looked around Newschoolers, I think it might be safe to say you know about FREEZE already. But I think it's reasonable advice, so I'll leave it in here just in case you don't know about it. Cheers.
