TAD 6550a-STR vs other re-issue 6550

This has been hashed out a bit, but I can't seem to find the TAD vs. Tung-Sol or other reissue 6550's I'm looking for.  GL KT88's seem a dry and uninvolving to my ear in the VPI 299d.  I loved the Winged c 6L6GC's in my previous Primaluna, but can't use them now.  It's my hope that 6550's might be a little juicier....and the TAD's seem like they just might fit the bill. 
Any experience with them would be appreciated and any comp with other 6550's would be even better.  Thanks ahead of time....
