Mic'd amp and sansamp.
I've never used an unprocessed DI ever.
I did occasionally use the psa1 in front of the amp or even after the recording on the mic'd signal
I always take a di and also run my Hartke VXL pre into Warwick Tubepath 5 head into Warwick cab and mic with a 421.
In the mix I usually go with the amp.
Sometimes the di has better clarity and I use that.
I rarely blend the 2.
