‘Fly Fishing Line’

I bought this new fly line a few days ago to replace some cheeper line I got with the pole. The new line is White River Fly Shop™ CV2® Fly Line from Bass Pro http://www.basspro.com/webapp/wcs/stores/servlet/Product_10151_-1_10001_25195_175003001_175000000_175003000_175-3-1. It’s 2x as light as my other line and half the diamiter and its tappered. I made sure its the same weight as my other line and my pole wich is 5wt. I’m having a much harder time casting the new line compared to the old line. I am thinking I need to break it in. What do you think the problem is?

or where i can buy a salt water fusion- 50lb
or a website where i could find one?

I am a beginner at fly fishing and need a good fly line that can be used for bass and bluegill and handle flies that are small enough for bluegills mouths but large enough for bass to take it. I will be using a 5 wt. fly rod and a X4 leader. Also I need a floating line. Any recommendations and advice would be appreciated, thanks.

or can you just use a finer version of a monofilament leader line for the tippet?

For my science class, we are creating rockets made up of 2 liter soda bottles that are to be launched while hanging on a fishing line. We are not allowed to use chemicals or heat (fire), and liquid cannot spill out from the rocket. The rocket must be able to travel all the way across the room, which is about 15 meters in length. It also must be fastest in a race against an opposing rocket. What would be the most efficient way (and perhaps even the easiest way) to propel the rocket?

I heard it before but forgot… What can I attach to my floating fly line to make my flies sink?

What’s the thing that adds more weight. Say if I want to drop a fly down 8 ft?

Also, what is the technique called where you have a dry fly then tied onto that a trailing wet fly?

Thanks!

they each seem to have thier own thing in each price range……is one brand better than the others or are they really the same. I’m looking to put on some new line in the – price range

would you use an intermediate line or a fast sink line when fishing from a float tube on a lake or would you only use the sinking line if you were casting from the shore?
