I really like the 40-95 set of cobalt flats on each of my thunderbirds. After at least three years they're still going strong I don't remember them feeling sticky or grabby, but I do keep my strings clean with dunlop ultraglide 65 string cleaner and conditioner — which is sold as an alternative to fast fret, and like fast fret is just scented mineral oil with a felt applicator, but being in liquid form in a bottle it doesn't dry out like fast fret.
I've noticed that Thomann has the new short scale cobalt flats. I'm quite tempted to get a set for my Squier jag SS.
