What in your opinion gives you the best tone regarding volume settings on the DT25 (In full power mode using L6 Link) and HD500?  When you create a patch, do you set your DT25 at the desired master volume level and then adjust the HD500 patch level to a suitable level OR do you max out the patch volume and use the DT master volume to control the level?  Does it matter?  When trying to level out my patches, should I pick a relatively high volume patch, leave the DT at a particular level and just use the patch volume to adjust?  What gives you the best tube tone in a volume suitable for rehearsing/playing small gigs with a drummer? 

That all being said, here's what I did - tell me if I'm on the right track:  I plugged my guitar straight into the DT without hooking up the HD500.  I used the suggested settings on the card that came on top of the amp and dialed in the British (II) sound using the same channel volume and master volume (2 o'clock) as shown.  This seems to be a pretty good level as a starting point for where I want to be.  Then, I created a patch on the HD500 using the Park amp model and all the same settings as on the card - with the exception of the patch volume.  I then A/B'd the patch with the direct amp sound and used the patch volume to approximate the same volume.  By switching on and off the amp block, I was able to A/B pretty easy and it appeared to be the same volume as when I went direct to the DT.  Once I had it dialed in with a few small tweaks, it was a dead on match to my ears.

Is this similar to what you all are doing?  Do you find 2 o'clock a good place for the DT25 master volume as far as tube tone goes?  Any input from all of you is greatly appreciated!
