Thank you for the suggestions thus far! I've already gotten one vote privately for the Zumo, and also a suggestion to add Budgy Smuggler's new Italy briefs to my list of potential suits. Unfortunately, the Smugglers' website says the fabric isn't good for regular use in a heavily chlorinated pool, so I think I'd destroy them pretty quickly. :/
Here's what they look like anyway:
Red^^Speedo, that is a beautiful suit and I love the color, but it is not lined which is a little concerning to me if I were to use it at my uni's pool.
Also, underwearphil, I actually gave the Neptune Scepters special mention in my original post as being too skimpy for my purposes, and they too are unlined which concerns me greatly as they have a white front! Again, they are beautiful suits and I love the Union Jack one that you bought yourself, but I think they are too revealing in size and [potentially] transparency for me to wear at a relatively conservative university's pool. (I don't think I'd have the balls to wear them either way.)
SpeedoBear76 I look forward to hearing what you decide on too!
