hi everyone
Lately i have been looking for a fly line for my 10wt.I found some fly lines that say

The sinking section is 30 feet long with a 70 foot running line section, totaling 100 feet.

Does that mean it only sinks 30 feet down. Or does its sink rate slow after that 30 feet of line. Or that 30 feet is just the weighted portion of the fly line and the whole fly line sinks at a steady rate.

extra info: fishing for rock fish, 10 ips(inches per second, fishng at depths of 50-80 feet.

thanks. <><

trout, bass, sea bass i dont care its fishing. <><
