LOL! That made me chuckle. Don't ever say, "You can't do that" to Stan!
Anyway thanks for that link, Stan. I like the interactive crosshairs feature. I was using the Weddle site's calculator, lots of extra info (% pull, etc.) but no plotting feature.
For fun I plotted out my transaxle with the 185/65 15 tires I'll run and a 7000rpm max (red) and then yours with 195/60 15 and a 5500rpm max (blue). We're never more than 2 mph apart at any given rpm. All roads lead to Rome when you've only got 4 cogs I guess.
