Question for those who have used the Viper VX10

[DangerCow]

I currently have a DEX210 with the Tekin RSPro, and hate the reverse delay soooo much (yes, I use reverse as a back-marking club racer). I am building a DEX410 and need electronics for it, and wondering if the VX10 reverse has less of a delay? My other option is the Orion something-or-other.

Thanks for the insight!
