We constantly fish larger reservoirs around here from a boat mostly. I stumbled across the Diawl Bach last spring and started fishing it in a two fly indicator rig during spring/fall midge time. A very old Welsh pattern. The DB seems to work just fine if tied thin and sparse as suggested. It's so easy to tie you can throw together some variations and try 'em out. Zugs and Princes are old standards and will work everywhere. The DB fills a stillwater niche.
