ta0- In my next rev I made the top 10mm longer and added more material around the shoulder. This seems to have solved the instability so I claim success on this shape. When I can get more tips I can see about trying to fix Big Blue. I am considering just going to emachineshop.com and ordering tips.
Jack- When your right your right, I get obsessed. I make the string the old fashioned way with a 2x4 , hooks, drill and a lot of room. I get good results although I am limited to about 8' strings.
mailman- I have gotten really nice results with the round shape for the smaller tops and decided to try it for a large top. The large top plays great although I wanted something more maneuverable for certain tricks. The material that bulges out around seems to make certain moves more challenging. I think this latest version I made is great but I will have to play with it a bit more before I decide if there will be more revs. I am currently working on a smaller version of this top, (think jumbo short circuit). I think this could be a fun shape.
Sabaspin - Thanks!
