Glider Handling Question

In this month's Gliding International article on the Ventus 3, Aldo Cernezzi writes, "According to Berd Weber, I flew with a relatively forward CoG, which may have an impact on roll speed". This got me to thinking of my own anecdotal experiences with very forward CGs having a negative impact on roll rate, and I think that a forward CG does degrade the roll rate. But I can't figure out why that happens. Can anybody explain it in simple terms?

I don't know, but I've found that in some gliders lacking in roll rate (in particular the original Janus) it seemed to help to unload the wings. e.g. pull up a bit, then push forward to reduced G and roll at the same time.

This also ties in conveniently with reducing from cruise speed to thermaling speed :-)
