Trigger Types Tutorial Please

I'm still new and trying to understand all the different trigger types, especially for competition air rifle, air pistol, and small bore rifle and pistol. I've tried searching for something that just lays out the different types of triggers and describes them, but I'm not having much luck. If you know of a decent tutorial, please link it. Otherwise, please feel free to provide whatever information you like about the different types of triggers.
Also, I'm struggling right now to hold sight picture on an Avanti 753 while pulling the trigger, but the bull moves left/right on me during the trigger pull, and I'm getting significant left/right spread. In your opinion, will I benefit from learning how to shoot with this trigger, or am I just wasting my time?

I think trigger pull is nearly the whole game. If you learn to handle a crap trigger it will certainly be easier with a good one.
If your groups are going side to side, you are almost certainly "pushing" the trigger.
I had it happen to me at my last AP match. Fortunately, I had a backer target to check my zero and it told me I had a problem. Once I knew, I was laying for it and that was the end of it. I also made a modification on my trigger after the match, so it won't happen again.
I also have the remedy of being able to pick the brain of John Zurek and Steve Reiter at my leisure. Love it!

In amongst those 2300 posts of snark and PCP denigration is the occasional acorn.
Rover, you hit the nail on the head.
I really need to make an anigif of moving just the trigger finger. It would look kinda like this:

I'm not really sure what pearls of wisdom you're looking for with regards triggers but there is essentially just one or two stage triggers. Sure you can vary the pull weight on each stage and you can adjust the travel, and probably a few other things, but in essence that's the major factors covered.
Triggering should be a simple and straightforward act such that when you pull the trigger you do so smoothly and in such a manner so as not to disturb the sight picture.
As Rover says, if the sight picture moves as described then it suggests you are pushing the trigger, which in turn suggests the trigger is in the wrong place (or you finger position on it is).

In particlar the bits pertinent to triggering and pulling the trigger.

Thanks for the info.
Something I'd like to know is if a top competitor could use the Avanti 753 and regularly shoot 95% or better without batching, or if the limitations of this rifle would prevent that.
What do you think?

They are not used by any competitors on the world stage, but I don't know if that means they could shoot 95's or better. That said a more expensive gun (all other things being equal), will have a better trigger, likely a better recoil pattern (i.e. have almost zero recoil), be able to better fit you and almost certainly be better machined to a finer tolerance with a more accurate barrel and a better/less variable regulator.
Whether the gun and you can shoot scores that satisfy you, is only something you can decide on, and you can certainly still fine tune your shooting skills with it, before deciding when or if to upgrade.

The 753 is a SPORTER air rifle .... not an Olympic (Precision) air rifle.
The 753 is designed to be shot with a minimum 1.5 lb trigger pull, and even that takes some work to get it that low safely. Nominal is about 2-2.5 pull weight.
If you would like to see what some of the best (high school aged) shooters in the USA shoot go to the CMP website for 3-P air and look at the national records for the
standing stage in sporter:
http://www.odcmp.com/3P/Records.htm
Overall record is 96% ... from an EXCEPTIONAL sporter shooter.
Most records are in the 92-93% range ... again, VERY, VERY GOOD sporter shooters.
In short, the 753, 853, 953, 887, 888 triggers are not in any way in the same class as the Olympic style gun triggers.
So, possible? --- YES, but not likely. Especially not regularly.
The rifles are capable of it ... we see many 100's in practice and matches in prone, but the trigger is really the limiting factor of the sporter rifles ... by design.

Thanks. That really helps put things in perspective.
