RE: Looking for an intermediate slope glider recommendation
DS? Get the JW. No other EPP plane does it was well. I'd avoid the Redback, having heard some negatives about the kit. If you want to do DS with 'glass, the Destiny rocks. I love mine. Very reasonably priced for what you get, and really, really fast.
If you're perhaps more frontside inclined, then I'd look at the Le Fish or Guppy from Leading Edge Gliders.
Check out Soaring USA and F3X.com for other planes.
