FWIW, I've had problems with Foma/Arista.EDU Ultra VC RC paper silvering out when framed in (admittedly cheap) frames. Loose prints seem to last longer. Of course, there may be a problem with my technique, but I've not had these problems with Agfa (now Adox) MCP 310RC, which is the paper with which I started and have used the most of to date. I have less experience with, but also have had no problems with, VC RC papers from Ilford, Fotokemika, and Kentmere. (I have framed samples of all of these with no problems to date.) Problems tend to crop up 1-2 years after framing. My oldest framed Agfa photo is 5 or 6 years old by now, with no signs of problems.
Of course, if you're just learning, image stability may not be that important, but I expect at least some students will want to display at least some of their photos. If I were just starting out, I'd rather pay the extra $5 ($33.99 vs. $38.99 at Freestyle for Arista.EDU Ultra (aka Foma) vs. Freestyle Private Reserve (aka Adox)) for photos that won't turn ugly and useless in a year or two.
