OK i measure a Deluxe Tinker at 21.9mm and 125g, an Explorer in the past at 20.7mm (non plus scales) and 101g. So you're looking at just a little more width, but substantial weight increase unless my sample is particularly heavy due to its age. If I can locate another quickly I'll compare that.
Update: Checked my inventory list (not very up-to-date) and I only have the one Deluxe Tinker. I think the weight decrease would make the Explorer quite a bit better in the EDC department, even if the width reduction is minimal.
