I use both single and double reeds, and I prefer double. Although some doubles do stick once in awhile. For $20-$30 bucks I would go with an Echo poly or a Primo's wench. Both good calls. I have locked plenty of redlegs up with both calls. As for better calling, practice until you nearly pass-out. Then do it again. Air pressure, and being able to regulate it is the key to calling. There are also video tapes on calling. "The Art of Commanding ducks" by Phil Robertson is a good one, and there are others. Hope this helps.
