It took me a while to react on this topic, but here I go as well:
IS87/2007 = OK
IS101/2009 = OK
IS122/2008 = OK
US147/2011 = OK
Unfortunately, we mostly hear negative things from "unregistered" users.
It would mean much more to me, to hear negative things from registered users with 100+ Posts, like Ken, markh, etc ....
I don't want to say that I don't believe "unregistered" users, but I'm sorry, they are just less trustworthy to me.
Again, don't let it stop you of course to criticize. When there are structural problems with certain boards we ALL want to know. In some cases pictures could help.
For my son, I've bought a few years ago a non SB 2nd hand board of 2009. After 1 year I already noticed soft spots just in front of the front foot straps. I hated it as well.
