I think it's possible to have both, you just have to alternate between one and the other, speedo and thong, and after a few weeks you'll have both tanlines :D
Yes ! It's possible. I alternate between narrow waisted speedos when I go to family beaches and public swimming pools and thongs on quiet/low crowded beaches (even in mountain hiking).
I've had both of them.
These last years I've lost my thong tanline because I wear backless thongs and g-strings. It's highly recommended to wear the same kind of thong for get a well contrasted tanline.
Definitely, I prefer thong tanlines, but I enjoy speedo's as well. However, I'm willing to lost my tanline as long as fully enjoy my passion for small under/swimwear and wear all kind of sexy thongs, jockstraps, c-strings, socks, plugs...
