tandem rigs???

I normally tie an additional piece of tippet to the eye of my top fly, generally somewhere between 18-24".  I am not a big fan of tying the dropper to the bend because it inhibits any motion the top fly may have.  The only time I tie droppers on the bend is when I want an emerger or wet to trail a dry.  Probably the best way to do IMO is to leave a 4-6" tag from a blood or even a surgeons knot attach top fly to that.  I just often get lazy and stick to the way I have always done it, I should think about using the knot-tag rig more.

I tried it all when fishing with droppers and the best way I've found is to tie into the bend of the hook on the first fly. I've never broken off a fish due to a knot slipping like I have when trying to use the tag of a blood knot and it doesn't get tangled as much tying into the bend of the hook.

I've had awesome success fishing for steelhead this way under a strike indicator / float can't beat fishing two sucker spawn flies in this manner.

Good Luck

When I teach nymphing and when I nymph myself, I set up my nymph rig in-line, meaning the shot is on the tippet, and the tippet that attaches the second fly is tied to the bend of the hook on the first nymph. You will tangle much less doing it this way compared to tying a fly or adding shot to the tag end of a blood knot.

There were 2 articles this year in magazines about this thing hehe.Perhaps I am lazy or set in my ways, but I still like to tie off the bend of the first fly. Although like mentioned above I did remember once or twice to leave some extra bit of a tag, when I tied some tippet on and tried a extra fly once and used weight another time. Makes alot of sense to tie off the eye, if you have the space to do so.
