I'm not really sure a 7/8 Delta with 85 grain tips would get me any closer to what I've achieved with the 6/7 and 125 grains tips. I'd expect the wimpy 85 grain tip to perform as well as the 77 grain tips of the 6/7 delta. By adding the heavier tip to the 6/7 I've essentially increased the head weight to that of a 7/8 but doing so where it's needed for a larger fly. I've also increased the length by a couple of feet. So the loading is the same as a 7/8 in this configuration, casts and loads nicely. Smooth accelleration and Line speed into the back cast is key to keeping the head stable at the hinge point. Snake roll has been tricky, but doubles and singles go off without a hitch. I suspect the snake rolls will come along as I put some more time into this new line and configuration. I will consider a trim off the front of the belly if needed. Thanks, Brian your advice is welcomed and valued. James.
