Thanks yoboy, I was thinking along the same lines. I want to make sure the Regal is settle in for sure based on their poor success rate to begin with. I'll look around for another tang option.
LisaD, In looking back through my pics, the oldest one I have of the T. deresa is from May '01. Pretty close to when I got it. All of about 3" IIRC. Hard to believe it's even the same clam, but I assure you, it is.
