Bug HLG

I'm just starting my lightnin bug build and I have a question. I've used the search function to try and find an answer but come up empty so far. On the plans there are two drawings of the tail group, one much larger than the other. I plan on makin my bug a dlg so I'm thinking that the larger tail group would be the best choice but I'm not excited about the extra weight. I could make the fuse a inch or so longer to help balance without adding extra weight but hat still raises the overall weight a bit.
