Sound reasoning. I mentioned my own preference back on the Loverslab Forums as well, it's purely aesthetic--and yes, being that massive they could look odd without enough sagging. I should've mentioned in the above pic of Rachel that I also like the comparative size as well as sag--both reduced. Then again, I'm a long-time fan of the franchise who just started playing around with mods for the laugh of it, so I'm used to seeing them in a more modest light (usually though not always much so).
Overall, I think most people are very happy with the direction you're going, so I wouldn't fault you int the least. That's why I've kept an installation of your BP 0.99 (also the bikini recolors, which are awesome).
Moisture textures do look better in the more recent versions, so it's all a trade-off. Don't take this as a complaint so much as complimentary feedback. I do hope you'll take a crack at fixing the Speed bikini issue, but you've got a lot else to do I'm sure.
