Looking into Buying a B&S OPTIV Performance 2z443 or 664

My company is looking into the possibility of purchasing an Optiv Vision System. I am likely going to the Irving Texas Hexagon office next month for demonstrations of several platforms. Currently we have a handfull of parts that a vision system would be ideal for but I am still not sure if it's the right way to go. I am very unfamiliar with the CMM V and the CMS 106 laser Line Sensor. I know if we upgrade to a Global with a TesaStar head we could incorporate these options and perhaps that would be adequate enough to overcome our issues. Truly I am just not very knowledgable with these systems and I am hoping for some feedback from you guys. I would ask for anyone to list questions for me to ask while I am visiting Hexagon for demonstrations of these options. The more ammo I have the better. I will take all the insight on the subject I can get.

What do you like about your vision system?
What do you dislike about it?
How comparable to programming a standard bridge CMM is it? (I realize that basic training comes with the purchase and I will no doubt need even more)
Is the R&R gauge fixturing compatible with the table on the Optive system or will we need new fixture tooling?
Can I edit existing programs written in PC-DMIS CAD++ with new code from the Vision Pack and run them on the vision system or will I be stuck re-programming from scratch?
Is it imperative that I have the system in a climate controlled environment? (Currently we have a B&S ONE 7-10-7 and our lab is typically at 76F.)

These are just some of the basic questions I have but I am sure there are much more that I need to be asking while I'm sitting in front of the thing at the Hexagon office in Irving. Our San Antonio facility is looking at the Zeiss O-Inspect 322. For my money I want to stick with B&S and not be bothered with Calypso. Then again, maybe I'll learn something here and be more open minded?

Any feedback is appreciated!

Thanks
