Got my CGR 7/8, and tried some lines and casts.
What I want with this rod is to be able to make quick boat length presentations to fish sign, and also cast (some) distance, all while sitting in a kayak, and quick out of the gate - a shotgun start. Mostly, do it all with a minimum of false casts.
The CGR 7/8 should be capable of this.
It will cast the leader alone, which only progressive-taper glass and a few cane dry fly rods will do.
My long S-glass (para) and graphite line cannons will make the long casts, but from zero, they all require several quick false casts just to get the front line taper through the rod - this isn't a problem if you're wading, and pre-armed by already having the front taper through the rod.
Started with a 7-wt slime line, thick leader and tippet, only 6' total. The taper and belly is 35', stripped out again that much running line.
With only a foot of front taper hanging from the rod tip, I was through the belly in 2 false casts, and shot the rest on the 3rd stroke. This is exactly what I want, and the rod does it perfectly with the correct line.
When I tried a WF7F Rio Redfish taper, the result was Fail - this line behaves incredibly on my long fast rods.
But the line will not shoot on the CGR 7/8.
It's because this line has a very long front taper followed by a short belly. The line taper and belly handles and casts beautifully on the CGR - like a Double Taper trout line - but the rod will not shoot the back taper more than a dozen feet - not with all my coaxing and best haul form. Shooting the belly shouldn't be affected by the long 7' furled mono leader plus 5' fluoro tippet that was already on this line.
Noteworthy, and not surprising, the CGR 7/8 would cast the long leader alone beautifully.
So I dug out my 333 WF8F Salt Rocket taper, which is on the reel and rod in the photo above.
Up front, it also had a total tapered leader and tippet of 12'
With the 333 WF8F Salt Rocket, it behaved exactly the way it did with the slime line, and I was able to duplicate the exact same cast.
A foot of front taper out the rod tip, holding my long dangling leader, 2 false casts through the belly, and 3rd stroke, shoot additional running line equal to what was already in the air, and more.
The rod did ask me to control my arm movements and use my haul.
So the CGR 7/8 likes the 7-wt slime line taper, and it also wants an equally short front taper on the floater, which the 8-wt rocket taper has.
A warning to try your lines with this rod if you want a shotgun start and be able to shoot out to 70'
For my shotgun start, I want total leader and tippet no longer than the rod, so it's ready to pick up and start my cast.
I'm going to use 50" mono furled leaders, which I'll balance to the rod length with fluoro tippet.
Borrowed these photos from a friend and parallel discussion of this on FFR - here is the line taper that works well on the CGR 7/8
Here's the type line taper that works well on long graphite rods, but doesn't work well on the CGR 7/8.
And this result surprised me, I thought this line would work great on the rod.
