Your best answer would come from your own personal sales experience. In my experience, I found there is a demand for both types, and buyers select one over the other for a variety of reasons. So your results will vary depending on your sales venue and the type of buying clientele that show up. Be careful to NOT bias the result. For example, if you guess that twist style will sell better, and then present a higher percentage of twist vs click, you will likely sell more twist. That will lead to the conclusion that twist is the winner. Same discussion can be made for the other factors, such as quality level of kit used, and wood vs non-wood, etc. Point is, if testing the popularity, test with a level playing field. That way you get accurate results, and greater overall sales, as you refine your product mix to match your buying public.
