For those of you that have actual experience, Which do you prefer? The Apex with the 4 cyl or the viper with the Nytro motor. Apples to apples. Performance, ride quality, chassis, handling etc. I loved my Apex and struggled with the feel of the Nytro. Just couldn't deal with it after I built it so I sold it and stayed with the Apex. I'm leaning towards a new Viper. There are no dealers within 400 miles of where I live so a test ride has been out of the question. So, opinions please....
