By 'non classic woods guns' I mean that there is no such thing as a woodsball gun
The tippmanns are good guns and often seen in the woods, the underlying principle of 'speedball' guns is on the ease of ergonomics, lightness and speed
(By speed I don't mean high rof but the ability to select a target, point and fire)
A speedball player wants those functions, and the lack of them becomes obvious in a close proximity open speedball field. In the woods this could be less of a factor as you may not be responding to multiple target opportunities a over the field at once
So the so called 'woodsball' gun exists
A speedball gun still has its advantages in the woods
'Tactical' elements - EG having rails is common
The problem is making good use of them without just putting on pointless extras
Adding grips aids ergonomics customising the gun to you
Adding cameras contributes to your enjoyment by watching again and showing your play
Adding lights helps (and hinders) night or CQB play
The rest may just be weight
Sights are a common add on. 99% of the time they are added weight and look pretty. You can train your eye to use the gun as you should use a red dot - thus removing the red dot from the equation
A telescopic lens give people tunnel vision (if they can actually use it with their goggles)
But - with the right practice, and a lot of it a telescopic sight can contribute to some players
We have a guy who's saying is 'if I can see it I can hit it'
With paintballs it's bang, bang, bang
With first strike it's bang
However he is an accomplished shooter in a variety of disciplines and puts in the time to practice, know the ranges and be able to know where to aim
The best thing to do is get hands on with a few guns and see. What's good for you and your style
