Quote - I have P4/5/6/7 I use P7 with SR1.1 for most everything now. Very stable for me and I don't have a big computer. I using an old one right now.

Also has multi rendering, better clothroom, morph brush, improved material nodes, better use of OpenGL, faster when defaults are set to a reasonable setting. Every version has been better than the last.

I only use the older versions for testing and they will not be going on my new computer when it gets here, only P7 and all the others runtimes.

 

Much like you, I have P4,P5,P6 and P7 installed.
I pretty much use P7 most of the time. I have to use P6 for PuppetMaster though.

I also like the new MorphingTool with Poser 7.
