Rimefire Sports....ultra match hammer and sear for 10/22

[Until the Angels Fall]

I am looking to upgrade my 10/22s to get a better trigger pull. Is it worth it to get the Volquartsen Ruger 10/22 Ultra Match Hammer & Sear? ($65 in total) Or should I just get target hammer, target sear and target disconnect? ($90 in total) IS there much of a difference between the two?

Thanks, UTAF
