Building a indoor golf simulator. I have the space to have a TM4, I like that it is set back, love the software/video, education tools, and I really like JNPG for sim play. The GCQ is obviously outstanding but I'm not a fan of only being able to use the FSX, not a fan of the courses.

Is TM data indoors that bad? Will it result in unrealistic sim play. I'd love to hear from a TM4 owner. I appreciate any advice!
