Suspension software.

So I bought Front Suspension Geometry Pro a few years back. Not a bad program for the money and I like that you can add shims. I have yet to hear of someone using this program however

Next one I was looking at was Susprog. Does front and rear for a decent price but again, have yet to see anyone use it.

Then of course there is the one everyone seems to use, Performance Trends. I'm thinking there must be a reason most of the pros use it. Only problem is the full vehical version is out of the budget right now. http://performancetrends.com/SuspAnzr.htm

Should I just wait another week or so and get Performance trends full or stick with what I have?
