Ok, a tied on leader question

[joedog]

I and a fair amount of the rest of you tie on floro leaders.

So do you just tie a Floro leader when using braid or are there other techniques that maybe you need/want a lighter or heavier main line than leader line?
I tie leaders on braid but I also need/use tie-able wire(pike) on Floro, Mono, braid.

Next as most know I'm lazy.
So I have a tendency to tie on like 3 foot leaders in anticipation of lure switching and reties. Tying a wire to main line isn't always the best done in field.
I do use a speed clip when it's suited but there are numerous presentations that actually work better with a straight tie on.

So the question,
How bad is it for that TIP guide having a knot running through it time after time after time. Then when bringing in a fish that same knot comes back with extreme pressure as knot slides through guides.
I do the old tissue through the guide trick and haven't noticed any 'damage' yet.

Finally do the new'er' macro guides make this worse or better?

Oh and the 'don't use a leader ever' option really won't work with pike stealing Ten Dollar Lures.

So what what do you folks think.
