Personally, if I could start all over again those many years ago, I'd choose all three: *Drosera capensis, Nepenthes ventricosa, and a VFT.
* That way I'd have built up a bigger collection of CPs by now. *Oh well, if wishes were fishes I'd be d***** tired of fish *
As for your question westie, once I discovered that my VFT needed purified or rain water, it was easy to grow. I use the tray method and they grow fine even in the dry climate of the Colorado Rockies. I just received a couple of sundews and Nepenthes ventricosas a couple weeks ago, so I can't vouch for how easy they are to grow yet. Both are doing fine in open top terrariums so far.
It's always the first step that is the hardest, no matter what you are beginning .
