Legsuit for serious swimming

[Precipice]

Can anyone recommend a legsuit that's good for a lot of lane swimming?

I've been swimming in a Speedo Endurance(+?) costume for years. I used to wear that to the city swimming club and I've been pleased with the quality of that, but I'd like to get a costume that's not cut so revealing on the bum now that legsuits seem much more available. The obvious choice of the Speedo legsuits all seem to come with a bust liner and I really don't think that's something that I want.

Forgot to add that I'd prefer a standard racerback back for the top. Every other sort of cut looks odd to me! Although I suppose a covered back would also be all right.

I like my DHB suits. I have an Aeron legsuit with no bust liner at all, but also wear a Hydron legsuit which does have an additional layer over the bust - no cups or anything and I don’t find much actual difference between them (I’m a D cup). The Hydron is generally cheaper than the Aeron. (I bought mine as great bargains from Wiggle before it’s sad demise).

Maru. and saying "serious swimming" isn't likely to make others feel comfortable
