I'll be replacing my BB loaf mold since the liner doesn't fit squarely in the mold. It makes my sides wonky which drives me insane. I'm with you on loathing lining and am totally willing to buy a whole new mold to avoid the hassle and wonky sides. I sometimes do high tops, but I just tent saran wrap over them using strategic toothpick placement. I love that the Nurture ones are okay for CPOP (the BB one isn't). I don't CPOP very often, but I like to have the option.
I've got the American Soap Supplies Tall & Skinny mold that I LOVE. It takes about 40oz though so I'll probably be in the market for the 2.5lb Nurture T&S one eventually. A 2.5lb mold makes it so I can try out 2oz of FOs at a time at 1oz ppo strength. That's the perfect size for a hobbyist FOHO like me. And I think I just talked myself into the T&S one this Christmas too...
