Thanks misterling and carlmeek, your responses really put things into perspective for me. Being completely new to this world it's improtant to get views from a broad range of people so that I can make the most informed decision.
Right now, for me, it looks like I'll be heading to the PPL(H) route as I'd like to have the opportunity to fly in Southern Africa. I think the Class 2 will be ok for me although I'll be limited to daytime flight due to colout vision deficiences. Unfortunately this has kiboshed my CPL(H) plans.
