Following in ice's footsteps thinkig he messed up and two stoke had it right I came up with the following.

Ok so I went and ran the boat as shown above and here is what I found.
You really get what you pay for, most of these cups use an aluminum underwire which flexed too much while getting on plane. One had stainless which did help but the cross spray from the tips killed my top end.
One had vent holes on the top (looked alike like lace), this caused too much cavitation could not even get on plane.
One had extra padding to increase the cup size; while it makes everything thing look good, planing, engine sound, RPM's its all kinda fake because at the end of the day I had the same results that I started with.
I am not going to tell you how much cup was added from fear of being beaten.

I'm planning a major expansion of our facilities & production capabilities this winter so we can move forward with newer designs.
Back to this thread .......... "duck tape", "correct cup size", "cup venting" & the in-depth testing with the female cup devices shows how this community of performance boaters will go to the extremes to find that last little bit of performance left in their boats!!!!!! This thread has become very entertaining indeed!!!!!!
