That's interesting, as I have run across tequila connoisseurs who say that there are excellent blancos that do not, to use the OP's term, have a "bite" to them. Maybe these are those.
One mentioned here was Mastro Dobel Diamante. From there website "A rule-defying blend of Extra-Añejo, Añejo and Reposado Tequila, aged in the finest European oak barrels and double filtered to produce a crystal clear liquid renowned for its character and smoothness. Recommended to be enjoyed neat or on the rocks."
Here is a website that list more of the filtered aged tequila from 2014. There are probably alot more now:
