Spey leader formula's?

#1
I'm looking for a Spey leader formula. I have been using Lefty Kreh's Basic tapered leader formula but I do not know if it was intended for Spey fishing. I've been playing around with different (my own) formula's but do not seem to come up with a perfect leader. (If there is such a thing.) Any advice would be helpful.

This thread is sure to take off!
If you mean when fishing a dry line, I generally use only a rod length section of 10# Maxima if the fly is unweighted and not too wind resistant.
If using a weighted fly, I only use two sections. The butt section is usually half a rod lenth of 12 or 15# Maxima, surgeon knotted to either a half rod length of either 8 or 10# Maxima.

When using sink tips, I use a 3, 4 or 5 foot piece of 12# Maxima, depending on the fly and water clarity.

Do you still get good turn-over with two sections? Or is it because the line speed is more than a single handed and the fly will turn-over anyway?

I use the Lefty formula as well and for those who aren't familiar with it, it goes something like this.

Start off with about 5 feet of 40 lb. followed by 18" of 30 lb., followed by 18" of 20 lb., followed by 18" of 15 lb., followed by 24" of 10 or 8 lb.. I use blood knots for each of the connections. For the larger diameter line, 3 turns or so work better because they'll seat. Use some saliva to lubricate.

I do not believe that you get good energy transfer if you only use two sections. The fly line is quite stiff in relation to the leader and it's important to use a large diameter monofilament to transfer the energy correctly. As a test, take the same fly and cast it with a leader tied from 1 or 2 sections and then from one where the diameter is stepped down. I think it makes a huge difference in the cast.

If I need to make a longer leader, just add a few inches here and there and before long, you've got a really long leader. I generally fish with a 12-14 foot leader on my floating lines and about 3 feet on my sink tips. The one exception is that I treat the type II just like the floating line, I add a very long leader to it.

I have not found a better all-round leader than this one and the other advantage is that one can replace any given section if needed. I never by leaders anymore. I'm a big fan of Maxima hand tied leaders.

One additional item, for this time of year, I use a Rio mid-spey with tips. I remove both of the last two sections and replace them with the sink tip compensator and then use either a type III or type VI tip with an unweighted fly. That's been getting the flies right to the bottom.

I use a level leader for floating work and level for sinktips. Makes it easy and I do not have problems with turnover.

Problems spey casting at times, yes, but turnover is not one of them.

No problem at all with turnover. Actually it's possible that the line speed when spey casting is generally slower than with a single hander.
I just try to keep this fly sishing stuff as simple as possible.

Thanks guys. I think Steve just reinforced what I've been working with.
(Lefty Dreh's formula) Although I have not tried the formula in 18" increments. This is a cool Web site. :)

For floating spey lines, I just needle-knot on a permanent 10-foot butt section, usually consisting of six feet of .022" Maxima Ultragreen and four feet of .020" Ultragreen, ending in a Perfection loop knot. To that I simply attach the same 4-5 foot leaders I use with sink tips. They turn over fine.
