No have not tried the CSI UV DIP.
I have been real happy with Spike It and the results.
I have tried the pen and the spray can of Spike It.
I personally still prefer the bottle.
Like just about anything with regards to fishing it will become whatever your personal preference is on how you want to use it and the application method.
Good luck with whatever you decide on.
A Thermocline Lure from TODD and Belinda Box in Black Emerald Shiner with a Chartreuse Spike it dipped tail is wicked on just about any lake year round for Crappie.
Them Crappie love to THUMP IT!!!
