Thanks guys for all the comparisons. I wanted the 59" to have a good wind plane and the precision factor. I'm considering the 51" just because I like the Slicks so dang much and everyone seems to really like the way the 51" and the 71" flys. I have both the 48" and the 68" Velox if I need the wild side, but to me the 68" is pretty precise as well as floaty on e-power. Then there is the 48" Super Viper, just not crazy about the looks of it. 3dhs gives us so many choices......isn't it great! It's going to be the SV for precision, or the 51"Slick so I can see what all the Slickness hype is about, maybe I should just buy both.
