RE: New to archery... opinion?
Jenna, welcome to archery, welcome to HNI. You've picked a great place to learn.
Your a little light in the bow dept to really recommend a mechanical. I'm curious if you know your arrow weight and speed?
There are some fantastic fixed blade heads that will work great for you. The G5 Striker, Muzzy MX's and standard Muzzy's, Wasp SST, Innerlocs etc... many great heads, just keep them razor sharp.
Practice and become the most efficient archery you can be and remember to have fun.
