okay. After much testing and comparison, I am ready. But first, I am truly sorry for not having my camera. I wouldn't have said anything about anything if I had known I didn't have it here. Talk about dinglefritz!
As soon as I can post pics and I will make sure to include a pic of the top.
So, on with the show:
First, I'll speak to appearance. My Zap is about 4 1/4" high and 2 1/8" across. The RockZap is 4 1/2" high, and 2 1/2" across. The weight of the two is about the same, in spite of the size difference, concrete and the beefier SSS heatport. I think this is due to the difference in density of the two myrtles. While the Zap has the usual density, the RockZap is made of a burl that was very soft. Rick described it to me as almost being almost as light as balsa wood. She's a beauty though, curly blond burl. And I don't mean to imply that the wood is too soft. It's not like it would dent easily. It just doesn't weight much. The wood surrounding the brass heat port of the Zap is about 3/4" thick, whereas the wood surrounding the cement encased SSS heatport is only 1/2" thick. The heatports themselves are different in appearance too. The SSS is much heftier, including the area surrounding the stem tip. The stem tip of the vapor tube also goes into the SSS a little further at 1/2", compared to 1/4" in the Zap.
From the first hit, you can tell a difference with the SSS. But what surprised me the most was that each subsequent hit was also impressive, until the stem was cashed. The hits were much more full bodied than with the brass Zap. For those of you who bought the 13.5 back in the day, sort of like that only much smoother (unless you get too much. Then, look out). As far as the number of hits per stem, well....I sort of lost count.
I do know that there were more than the old Zap. And the true test was when I took the "cashed" stem from my Zap and tried it in the RockZap and got two more good sized hits. Hits that were bigger than any I had gotten from the old Zap.
Another thing I noticed was that ambient temperature doesn't seem to affect the RockZap as much as the old style Zap. My vape station is right underneath an air conditioning vent. My Zap needed to "get up to power" a bit after being under it. The RockZap needed no such adjustment time. Solid hits right away.
All of the old stems and Tooties from Rick work in the SSS, as well as the stems from Ed. All worked well for me, and believe me, I tried them all.
Now for the comments directed towards me above:
reece - Good to see you here! Just so you know, you wont sacrifice the outer warmth with the new design. It still warms the hands and the soul.
chucku - I hope I answered some of your questions. As far as which is my favorite? Between the Zaps, I've got to say that I love this new SSS. I'm not sure what you meant by the vt. But, if you meant the TT, between the Zap and the TT, I have to say there is a tie. I love them both. I love the feel of both of them in my hands, I love the woods used, and I must say, I am a big fan/supporter of both Rick and Alan. Sorry....can't just pick one....
edited to add:
lwien, about the SS stem tips; I have the TT. Alan uses SS in his stem/tube tips. I don't notice any difference in usage between the two vapes, now that the Zap is made with SSS, using the brass stem tips in the Zap and the SS in the Top.
