Steve, First off, welcome to the board. You'll find a wealth full of information from the guys on here.
I really like my JIB. It works great on fox, not many yotes here. Don't worry about the size of the rabbit, it works. I would suggest doing some mods to protect the buttons or you WILL turn it on by mistake and have dead batteries when you go to use it. I got the deployment bag from yoters den and it works great. It protects the buttons well, plus it was well made.
Tried mine at night. But IMO it's not worth the hassle. Too much stuff to fart with for me. It did't take me long to learn that the less stuff you carry the better.
Good Luck.
