Both are fine, but its not clear from your post which you are chasing. And clearly it kinda matters to the people you are contacting.
If you have a specific set of challenges and you're looking for advice, then say so. If you have been successful and are looking to advise others then pitch that instead.
Given that my specific industry context is different from yours, given that your experience is likely in a different country (or city) to me, I'm not really sure what you're looking for, other than being away from home and looking for people to socialize with.
Perhaps it would be helpful if you articulate your goals better.
