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

Thanks to the suggestions here I got a pair of SIEMENS E80CC / 6085 for my MZ2.  Significant improvement over the GL’s that LTA provides.  Replaced the RCA 12sn7’s that LTA provided with a pair of GE’s and I think I prefer the RCA’s. Just got a pair of Sylvania 12sn7’s this morning.  Haven’t tried any of my VT-231’s yet.  Awaiting delivery of a pair of 1950’s Sylvania 12at7’s.
