I have not tried one of Jack Su's pipes. I did try an early Road Town and was not impressed. That was 2 or more years ago. I recently purchased another one. A bent Dublin with horn shank application. Cost around $70.00 on E-Bay.
Cost to quality ratio is excellent! The fit and finish is far better than I've seen on some pipes priced over $300.00. The junction between horn and shank is smooth and seamless. One of the keys I look at when assessing pipes is the tobacco chamber, right at the lip. I see lots of very talented carvers, that allow dye "splash", close to the upper edge. This is easily corrected with fine sand paper. If the chamber is coated, I look to see if there is any "splash" on the rim and if it applied evenly. The Road Town / HS ( Huge Stone ) pipes pass with flying colors.
The fall downs are ( for me ), the chamber coating has a slight bitter taste. So far, after 4 bowls it has become less noticeable. Stem button thinness and drilling is very very good. Stem in Ebonite. No sharp edges. Thin and very comfortable. Drilling through the air passage is ok. Not as open as I prefer, but more than acceptable. I have since opened the stem a small amount, which did make it better. The big down fall for me is the metal tube used to connect horn to shank, is a small diameter. Slight issue passing a cleaner. Due to drilling angle and not having the correct drill bit I may not adjust at my end. However the pipe, plus a few others will soon get to George, and all shall be made fine.
Since the above purchase I bought 2 more, yet to arrive. Both very similar in shape to the one above. Both ran around $70.00 on E-Bay.
I have emailed the seller and offered the above insights. They have replied and let me know they will take the suggestions to heart. I am told they are always looking to improve and do take suggestions seriously. As I may be in China in April I asked if I might visit their operation in Shanghai. That has yet to be arrange / confirmed.
I have no affiliation with the seller or the makers of the Road Town / Huge Stone pipes. I do not sell their products. I have no intention of trying to arrange that. I am however very impressed with the quality for the spend.
