How much better are the genetic blends that are coming out? Are these more expensive certified genetic varieties that you can't find anywhere locally that much better compared to those available at Lesco or Scotts/Pennington that are available locally? I know you should use good seed but are some of these varieties worth hunting down and worth the price? I just used Summit Seeds NuLawn blend: Bedazzled, Brooklawn, Midnight Star KBG, Paragon Rye, and Salem Creeping red on my yard. It does look good, great color, but is it worth the extra money and the added shipping costs compared to going to Lesco and getting some of their better seed varieties?
