I have read about Spectra kite string vs Dacron. Spectra is higher end and stronger, but it sounds like it is more difficult to tie knots in. That is the primary reason I felt like Dacron held an advantage over Spectra for small all purpose PSK line.

So thus far, it sounds like Dacron is a good all around line that isn't expensive. Knots well and holds up well, but doesn't resist UV rays for extended life. But for a PSK, the line can always be replaced.

Spiderwire Ultracast Invisibrade has an up on Dacron in that you can get a mostly clear version of it. It may be a bit thinner as well? On the down side, it is much more expensive.

How about the Coat & Clarks thread? Not too many comments there. Anyone know what the true strength is? It sounds like it would knot better than the other two options and be better for sewing, do okay for fishing and snares, and resist UV rays better. Has a good price point.

Any other summaries or comparisons? As you can tell, I'm attempting to build my first true mini/pocket kit. I have my regular personal size kit, but I need to be more select in the smaller kit.
