Tube rolling LTA MZ3


hi,
wondering if anybody has done any tube rolling with a LTA preamp? Just got one, my sickness immediately makes me wonder if I can make it even better! Anybody have ideas on weather the 12sn7 or 12at7 position would have the most influence on sound?  For me, (in my system, my ears) this pre is an upgrade from Pass Labs XP12. So much more dynamic and engaging.
thanks for any perspective, Ted

Have rolled NOS Mullard 6201's in place of the Genalex 12AT7s it shipped with. Smoother, less grainy but keeps the detail. Did not like any of the 12AU7's I tried including some NOS Mullards and Brimars. System seemed a bit lifeless.
