Ok, finally got Fauzi today and got back the N. Hookeriana, N. Bicalcarata and N. Rafflesiana ver. Brunei Giant 99. What happened to the second set was something I had regretfully done in a fit of anger which I promised to Esther never to repeat itself again. So, here goes, third time lucky I hope.
Separately, I realised there are so many variants at different level of attractions and prices but Fauzi highly recommended N. Ampullaria William Red, which according to him is the reddest Ampullaria he has seen so far. Must check it out further.
