i had a z1 and always filled up the factory ballast (800 lbs roughly) then added a 600 lbs fat sac in the walk way because the boat likes to porpous when you get it up to speed. At slow speeds the wake is actually better in my opinion. It does look like a 210 but its real soft and tends to list over more when cutting.
Upgraded????? huh? Told you to re-prop that Z1 and it would fix that speed issue. No biggie, I bet it swelled BT's head to trade you out of a Tige into a CC
I see your home lake on your profile is Lake Brownwood, as you probably know that is Tige's homelake as well given its location which is only about 50 miles from the factory. Come by or give me a call at 325-676-7777 and I will give you a ride behind a Z1.
