I've tried both tight and loose lashes with the Oregon grind I have in Vixen now. Running it at .020/.020 rather than .008 and .012 really woke it up. I had it at .020/.020 initially but I had some detonation issues so I tried tight lashing it among other things. I finally got rid of the detonation problem and put the lash back to .020/.020 and it made a huge difference in power. I'm sure it's all combo dependent.
