When I started I found someone to ride with regularly who was a bit better than me (Monkey) and a lot better (JohnD) rather than in a group. I did this too when I got the GS. So what you need is a good wingman
Riding with just one person helps a lot, you can watch what they do and learn a lot.
Personally if you can do that, its better than riding on your own, but a lrage groups not so good as the others say.
I'd be up for an eve ride with you except the eves are drawing in by time I get across to Wales now.
