What is the best polyurethane material (manufacturer) for casting clear parts?

What are some special processes required over traditional polyurethane castings? (e.g. heating RTV, heating materials, etc.)

Any particular issues with silicone (tin vs. platinum cure)?

Any information is appreciated.
