T130 won't cast on the CGR 7/8, so it would have to be T200.
you can use a zap splice:
searched out these instructions from an old post on another forum
I use a pin vise and push a quilting needle in from the back and out the front of the fly line.
Use the smallest quilting needle that will fit the small end of your leader.
I start it about 3/4" from the fly line tip, and start the needle into the side of the fly line.
You have to roll the line and pin vise back and forth to keep the needle aligned in the center of the fly line as you're pushing the needle through and out the front of the fly line.
Push it in close to the eye of the needle and then move the pin vise from the eye to the tip side and take up all the exposed needle that has come through the fly line tip. Pull the needle through the tip until just the eye of the needle is at the side entry on the fly line.
Granny knot the very butt of the leader so it won't pull all the way through.
Thread the leader tip through the needle and pull the needle and leader tip through the line.
Work the leader all the way through the line until you bump the granny knot.
Just outside the fly line tip. wet about 1/2" of the leader butt with Zap-a-gap (green-label, gap-filling super glue).
Hemos work great, but grab the knot and leader butt tag and pull the glued butt into the fly line.
Clip the leader butt tag close where it comes out the fly line . Put a drop of zap on the end you just cut.
Grab the line and grab the mid-leader butt and pull the joint moderately hard (you're squeezing all the air out).
You're done except for letting it all dry somewhere.
Good thing about a zap splice, it bottom bounces beautifully and glides over rocks.
Here's a Very Good pin vise, and I can't offhand find less expensive that will do the job, but they're probably out therehttps://www.amazon.com/Starrett-162A-Se ... B06Y5SG9LD
