G-Adventures Male Solo Travel

Hi,

I'm interested in doing a Colombia solo-ish tour with G adventures but I get the feeling that the solo-ish tours mostly cater to females - which I'm okay with - but I'd prefer more of a balance so I'm not the only (or one of few) male in the tour group.

Has anyone been on a G solo-ish tour where there were fewer than 3 males on the tour and is there a way of finding out what the M/F balance would be before committing? Also, if there are alternative companies that offer solo tours that are more balanced between M/F, would love to know.

Thanks!
