I am only talking weighted lines / full sink here, but how many of you over line when it comes to weighted line and why?
Just curious, cause I think about the bowling ball and the marble dropped off the leaning tower thing. 8)

Fly goddess:
Larger fly lines have the capability to sink faster than lower weight fly lines. You'd think it would be the same since they are both round and made of the same material. However since they both have a core a smaller fly line has a greater percentage of core than a larger weight fly line. Thus the larger the line weight the greater the sink weight.
The other issue is that if you have a line that is tungeston coated there is only so small they can make it. Rio's smallest deep sink line is about as thick as backing but it's line weight is a 7 weight. It casts well on a 5 weight but it still scales out at a 7 weight for the first 30 feet.

Are you sure?
We buy our lines useing grains for weight and then using density for sink rate. Like a type II (density) #6 (weight) head or line should sink very much like a type II (density) #10 (weight) head or line. Don't they regulate line weight/line length (30') to achieve line # and regulate line weight/line diameter to achieve line density (type)?
.....lee s.
you want to match the wt of the line to your rod for better casting
FG,
I think I'm with you on this one.
The sink rate of a line is effected by it's cross section/density ratio. This gives you sort of a 'mass' equation where the sink rate is relative to the mass of the line as slowed by the resistance of the water.
The big difference between a line sinking through water and a bowling ball/marble falling through air is the difference in 'resistance' caused by the water.
Air resistance is negligible for short distances, like 100 feet. So, two similar shaped items with similar 'masses' will fall through the air with almost exactly the same speed.
In water, the resistance plays a much greater factor, thus a line with a higher mass/thickness ratio will sink measurebly 'faster' than a line with a lower mass. A 'heavier' line that is 'thinner' will sink faster than a 'thicker' line of the same density, due to the effect of the water's resistance.
However, the difference between line weights for fly fishing won't be all that great. The 'fastest' sinking 6 weight line will sink only a slight bit slower than the fastest 7 weight. For fishing pruposes, the difference would be unnoticible to the fisherman. It's unlikely that it would amount to more than an inch difference over 15 feet.
So, it would be best in most situations to get the line that casts best with your rod in the particualr sink rate 'type' you prefer. I can't say if that's the rods 'listed' line weight or not, rods can cast differently with a sinking line than with a floating. Going one line 'size' either way is pretty much up to you.
Good Luck!

:wink: Never found one that did not sink to fast except when they didn't sink fast enough.

To complicated for me although I do understand FG's original question. :? To keep it simple, I use Teeny's T-200 for 4wt-7wt applications in not to deep of water. I suppose it depends on a rod's action a bit but all my rods handle it about the same.
The higher the T series the heavier the line and deeper it's gonna go in a reasonable amount of time.
Buddy Sanders, you put it soooo, perfect. Very good answer!
Rich, the good news is, Airflo just came out with a TYPE VII. This should be interesting line.
Right now I have found the DEPTH CHARGE to be the fastest sinking no matter what line sized, but rather by grain. I think it is much like the Teeny line.
Seems to me the different types of line....that is...Intermediate...through say VII... each have their own sink rate...put another way....a Type III no matter what line weight will all have the same sink rate...[within standards].
