I too, have lots of trouble getting that type of bow done right!!
lol I have asked the same question as well. What I did was sorta made my own templates for 4 and 5" bows...however they still dont come out like i want them. I am seriously considering buying the templates from The Brilliant Bowmaker just to get that style bow faster and easier.
I hate to spend the money, so I am still debating it!! Hope you master it soon..its really hard!
