S coil is a good stab. I use one and so does my wife.

If your bow is a little noisey
Put on some cat whiskers
Get some limbsavers for your limbs
Buy or build a string stopper
go with a heavier arrow.

These will help dampen noise and absorb some shock on your bow.

Also don't worry about having the newest latest bow. People killed deer long before anyone every heard of a compound bow.

Patience and practice is what kills deer.
