Opinions on sampler pack I'm thining of ordering

[Sime83]

Hi everyone,
I've decided to get a sampler pack so that I can sample a few different flavors. I like the medium strength leathery / chocolate / coffee taste really. Anyway, I found a sampler pack but it's enough money for me so I want to make sure what it contains are quite good. These are what are in it - has anyone got any opinions or experience of any of them?

Luiz Martinez Robusto - Nicaraguan
Chartan Robusto – Nicaraguan
Santa Damiana Robusto - Dominican
Casa Torano Robusto Natural – Honduran
La Invicta Robusto – Nicaraguan

Many thanks,
Simon
