I have close to 1000 hours in first a DG-300 followed by my Discus B flying cross country and competitively. My impressions mirror Marc's pretty close.. The DG-300 climbed well heavy but wouldn't run quite as well at higher speeds compared to the Discus B. Gel coat quality, pilot comfort and ruggedness all fall in favor of the DG-300. It has a smoother heavier car feel... probably because of the higher mass wings. The Discus B felt lighter and more responsive while maneuvering for thermals... also probably due to the lighter wing inertia mass.

A well flown DG-300 will do quite well against someone in a Discus B. But, as George Moffat said... even small performance differences add up for every minute of flight and the Discus will out perform a DG-300 in the long run.. But now, we have handicapped Club and Sport Classes, so either ship is competitive in those classes.

I like the SH factory and dealer support without the "DG Tax".

Very happy now with my Discus 2A.
