I've built or cast all of them.

SCIV = Corvette

TiCR = Camaro

Forecast = Chevette

I love my 7'9" 3wt Forecast, best blank in their line-up, however, the 9' Forecasts are not the way to go for a primary rod. SCIV is the way to go out of your listed options,
If it's your first build, go with the Forecast
