Brand new to this but want to get the most for my money

So I used an Airbow one and fell in love with almost everything about it (except the noise level). I was talking to someone about air rifles and was told that I should look into getting an air rifle and see about shooting bolts out of an air rifle. Then when I asked where to find out about my questions I was told to come here.

So now I'm here to ask questions and hopefully not annoy anyone with my questions.
So my first question would be, is it better to buy and arrow gun and shoot arrows or would I be happier if I bought an air rifle and figure out how to shoot arrows/bolts out of it?
And then how hard/expensive is it to convert an air rifle to an arrow/bolt rifle? And can they still shoot both arrows and slugs?
And then where do I start when looking for an air rifle that is able to shoot arrows?

Also I am looking to get this for cayotes and maybe deer as to size of animal.
 
Ok how about an opinion question.
I'm still looking at the Rex Ibex (new school carbine) but I was looking at some others and found the Seneca Double Shot.
Looks awesome. (old school rifle look that I like), double barrel (also cool as hell), and even more versatility (Slug, #6 or #8 Shot, or Bolts)

Does anyone have any experience with this rifle using all the different projectiles and switching back and forth. And if so how do you like it.
 
Ok I get that much, the only reason I'm wondering about it is because they are advertising it as a bolt shooter. I was wondering more if anyone has had any experience with shooting bolts out of it. I've seen videos of slugs and videos of shotgun shot but can't find any videos of anyone shooting arrows :mad:
@cheez I’ve seen someone address some of your concerns about shooting bolts in a review of the Seneca. Not sure if it was for the Wingshot or the Double Shot. I am of the opinion that rifling is necessary to accurately shoot Air Venturi air bolts.

Correct, need the rifling to impart spin,.......I'm sure the smooth bore still shoots them OK but I would rather have a Dragon Claw that can shoot Bullets and arrows real well.
