I would give it a try and see whether it is a group with whom you feel comfortable riding. About the advice, I have found that I am much more receptive to advice from my fellow club riders than my DH (who also rides with the group). It has become a joke because he will hear me listening to one of their tips without any problems when I just gave him an earful for saying the same thing. Also, most people will figure out if you are seeking tips or prefer to be left to try it out for yourself. I hope it works out for you.
