You will degrade the performance of your bow as you add fps to some extent. I read where the reason you bought the Switchback XT was because it was quiet. To add speed by going lighter on your arrows, you will pick up noise.

Tell us your exact setup and we can recommend changes but the difference you gain will be irrelevant to your needs.

You can go lighter on the arrows, noise will increase. You can go to a smaller string, meaning less strands, your noise will increase. Lighten up your string via peep, nocks, silencers etc....

You bought a shock free, quiet, vibration free slower bow...live with it. (not slow by most standards, just slower than others)
