I want to put yellow High vis mono on my baitcatser because it looks cool but im worried it will not help me catch fish. Is it bad or is it good?

It's neither here not there - some say bass are color sensitive, others say it makes no difference.

 

Personally, I keep my Hi-Vis line to braid, and have a colorless leader from that to the lure...and that's on spinning gear with only two casting rigs having braid, but those are loaded with Lo-Vis Green.

I've use Big Game Solar Collector occasionally. I've still caught fish with it when A, fishing a place they bite easy, B, fishing at the river where the current is strong. I have not caught fish where they are pressured using it, but I haven't fished it much there due to a lack of confidence.

 

I think it matters on pressured fish, but I think it doesn't matter on not pressured fish.

I didn't realize it was your first post, Howdy and welcome!

I have used yellow stren in ultra clear water here in michgian and down on lake guntersville.   I noticed no difference in catch rates between me and my partner using a braid to floro set up.

I use clear blue flourescent. 

I use straight hi vis yellow Sufix 832 braid.  It's the only line I can see anymore.  I catch plenty of fish.  The lakes I fish are always dirty.  I use a black sharpie to color 3 ft of the line.  I don't think it makes a difference but it's a confidence thing.

It's hard to enjoy fishing if you have to try and tie a knot with an invisible line, or see the line twitch on a strike.  Floro and mono (no matter what color) are invisible to my eyes.

I do use thick (25#) hi vis mono for fishing square bills.  I need the thickness to control depth.  This is a pure reaction strike so line color is not important.  I just deal with the frustration of my poor eyesight.

I also use big game solar collector with a 7 ft flouro leader!!

I have it on my dad's old vintage Garcia Conolon light action rod and equally vintage Garcia Mitchell 304 reel...  It's perfectly fine for stained, murky, type of water.

Greetings All,

I use low cost mono of different levels of visibility with no apparent difference in catching fish. I'm using mono from Zebco, and Bass Pro Crappie Maxx in the three different color offerings. I'd been using them in 4 pound test and they all work reasonably well for taunting fish. I've used them in spinning and BFS casting reels. They all catch fish, bass, bluegills, catfish, and etc. 

 

After years of using these different fishing lines I have developed the opinion the line color does not matter. I've not identified any significant difference in fish catching ability with the four different line appearances (1 Zebco, 3 different Crappie Maxx). 

 

Now I simply spool whatever happens to be handy and simply use it without any bias. Of course your mileage may vary. It could also be that fish in Southern AZ don't have a strong preference or adverse response to different line color because of the massive amount of sunshine with heat. Just $ 0.02 put in based on this fella's observations. Be well, Cheers!

I use PLine CXX in 6 pound yellow. It’s really good at 1st light and approaching darkness. Casting it is like a tracer, you can really track your cast. It’s easy to manage on spinning or casting. CX Pline in clear blue in 4-6

a very soft line and is easily controlled on spinning. Most of my gear I’m running Yozuri Hybrid lines up to 25. 
A couple are spooled w Daiwa Samurai FC. I still have 1 1600yd spool of Triple Fish camo line, it’s a solid line with a trio of color including a clear-blue florescent strip.
