One other thing I thought of, because I also like good TH even though I'm moving to sweet vapes rather than tobacco -- there's a flavor additive you can get, called "Flash" -- the only place I know for sure that has it is ecigexpress.com. It's not expensive, and I add a bit of it to sweet vapes like baked goods flavors; it's not a huge difference, but it does give just a bit more "throat tingle" even to pre-made ejuice that has virtually no TH at all.
Also -- no idea what hardware you use, but when I got a Kayfun, I found that the throat hit it offers is very intense; I even had to back down from my 85% PG, to 80% PG, just so I didn't start coughing with every hit. Since you make your own coils with a kayfun, you can mount the coil high, and the TH is amazing -- also the flavor, very clear and intense flavor with a kayfun, but the TH thing was very noticeable right from my first hit.
