I am trying to decide which of these two lines to try out this upcoming spring. I was wondering if anyone has used either one and what their thoughts, experiences have been. I mainly fish jigs and worms, so I like a tough abrasion resistant line that has little stretch. I used to use Yo-Zuri E-TEX Cobra line, but they have discontinued making it.

Evolution has less stretch

CX has much more abrasion resistance.

I prefer CX and CXX

Evolution is good line, CX and CXX are better.  Like Fourbizz said, it has less stretch, but it can be a little on the weak side in same sizes of CX.  If you are using smaller diameter lines, 10-12lb, go with CXX, CX is a little weaker but more manageable in larger sizes. 

I would have to agree with the comments already given, but one thing I liked about Evo was its castibility. I thought it was better than than CX and shoot, most lines would beat CXX. Then again CXX is known for its amazing durability and not castibility.

With Evo, I was able to cast to the other side of the river in 18 degree weather with less than about 3/8 oz weight and I bird's nested. I didn't realized my line hit the other side until I noticed my line dangling in the trees on the other side. The snow blinded me so I lost sight of the cast.

The picture below is my curado D with 12# evo on it.  Even with a rated rated to toss 3/8 - 1 3/4 oz lures, I was able to cast this little home made inline spinner that is less than 3/16 oz about 100 ft. pretty well. That is not too shabby when you factor in that my rod has no business casting something that light.  I credit the line.

If memory is a pet peeve of yours however, none of these P-line products will suit you. They have and quickly acquire memory up the ying yang. Fortunately it doesn't bother me too much as their traits far outweigh the memory tradeoff.

CXX

I've tried P line several times.  I can't say anything good about it. at all.

I've got several spools left over from various close outs I bought at

various times.  I won't even use it for catfish line.
