Once you get your KASL, I suspect that you won't need to rely as much on the sugar and honey to provide increased crust browning. I recently used both dairy whey and vital wheat gluten in an all-purpose flour and got good browning in the finished crust. It's a good thought to keep in mind for future reference, but it won't matter much once you get your KASL.
Your comment on using cane sugar instead of raw sugar raises an interesting point. I recently substituted table sugar for raw sugar in a "thin" version of Randy's recipe and could taste the sweetness more in the crust than when I used raw sugar. I used table sugar because I assume that is what someone like Papa John's would use. Maybe Randy can tell us his rationale for using the raw sugar.
Pizza screens are available from many sources, including several online sources and many restaurant supply stores, and occasionally even on eBay (although the shipping costs may rule them out for only a single screen). And they are very inexpensive (even the large sizes like 18-inch are under $10). I researched and experimented with several brands of pizza screens and concluded that you can't go wrong with brands like Adcraft and American Metalcraft (AM). Pizzatools.com also has very good screens but they are more expensive (I love all their products). I think the pizzatools screens are U.S. made. Almost all pizza screens are made in India today.
You don't want to slice pizzas on the screens. That will damage the screens. You might want to buy a pizza tray for cutting pizzas, or use a cutting board or something like that. Some people cut the pizzas on the peel, but I don't do that personally because of the potential for gouging or otherwise damaging the peel. If you do a Google search, you will find many sources for pizza screens, trays, etc. You will also find a lot of additional information, including sources,†if you do a search on the forum or look under the Equipment and Supplies boards. You might find it cost effective to make a list of pizza items you want to own and buy them at the same time.
