Winter bass fishing with boobies and a Di 7

Once again the awesome combination of the Di 7 fast sinking fly line and boobie flies has been producing mid winter bass for me. I normally use two #4 boobies on at once (like I would for trout) and have found that orange has been deadly once again. I cast out, wait for the line to sink and then retrieve the flies back erratically pretty much the same as I would do for trout. Not too fast but certainly not ultra slow either. The total length of my leader with both flies on is 2 meters. Works for me....Check out www.seanmillsflyfishing.weebly.com for my awesome DVDs and E books on fly fishing for carp and bass.
