Rocco, after I e-mailed you, I went to check out how the Zia mini grills would work with your 1.3 L Evernew (in the photo, Dale's was the 900 ml Evernew). I don't think the mini grill will quite work for your larger diameter cone. Probably you should go with the full size grill instead, even though it would be longer that you need. Or, simply find the right sized cookie cooling rack that you could cut down to the size you need.
Not to rush you, but I am dropping prices 10% on all of my Zia products during the month of May, if ordered directly through me (and not through QiWiz.net). Good luck with your Ti-Tri setup–I'm sure you will love it!
