We had a string thread a year or two ago and had a pick thread back before Hemi-Cuda got the banhammer, but it doesn't hurt to have another one.
I'm still using Dean Markley Blue Steel strings on my electrics. Been using them since the '90s, and have tried others over the years, but I keep coming back to the Blue Steels. they're the only brand of strings that I haven't broken (seriously, they're tough ass strings), have the tone I like, and last a loooooooong time before they start sounding dead. I love 'em. The sizes I use are dictated by the tuning; 10s for straight E/Dropped D, 11s, for Straight D/Dropped C, 12s for straight C/dropped Bb, and one of these days I need to pick up some 13s so I can try my VBT700 in even lower tunings. I'm not so sure that I want to go down to straight Bb/dropped Ab with it, but if I go the half step down to straight B/dropped A with it, I want to go up a size in strings to make sure there's enough string tension to maintain clarity.
The Bass currently has Black Diamond strings (can't remember the gauge), but when I need strings it'll get Blue Steels.
The Acoustics both get Martin strings.
As far as picks go, I've been using the Dunlop John Pettrucci Jazz III picks for awhile now. I had been using Max-Grip Jazz IIIs, but tried out some Dunlop Ultex picks and loved the tone I got out of them enough that I had switched. Problem was that I would shred the Ultex picks bad enough that they were only good for about 2 or 3 songs. When the Pettrucci picks came out I read that they were made out of Ultex, but were shaped differently. They're nice, thick & stiff, but have a kind of knife edge to them and come to that nice sharp Jazz III point that I like (actually, they're a have a little sharper point than regular Jazz IIIs). And they don't shred off like the regular Ultex picks. I like them enough that I've completely switched over to them.
