Questions about switching/adding casting reels to my quiver.

I've always been a spinning reel guy, as you can see in my previous posts

I did a lot of talking to some people and reading, and I don't really plan on replacing my Saragosas, because I've had great success with them and I'm the kind of person who likes to stick to what works lol...however I'm open to new ideas. I also like to keep the ammount of gear I have to a minimum, so overall versatility to me is very important.

However, even this smilies use casting reels

I'm curious about Abu Garcias, and the ease of transistion to throwing an Iron. I'm really not looking to start playing with birds nests, one after the other, and I was taught about the magnetic cast assist from the Avec.

I ask about Abu Garcia, because I've read great stuff about their quality, and I get a pretty generous discount on them.
Specifically the Revo series (Premier) for throwing irons
or the Alphamar if I plan to troll for halibut?
Thoughts?
