This could be a trivial question but....

Black Tortex Dunlops are 1mm. If Opeth uses those, that's the thickness.

I use Dunlop Tortex Sharp 1.5mm

For strings, I use Dean Markley 10-52

do you guys suggest using heavier or lighter strings for dropped D or lower tuning? Also, does anyone know of a website or have good Opeth tabs?
thanks
