need help with how to equip for sunday

Ok, I'm in a crappy merlin but I've at least trained to use warp jammers and stasis webifiers. It looks like the warp jammers usually come in 2 basic flavors: Long range and low jamming strength or vice versa.

What kind should I get? Am I gonna be going in close to other ships?

I would get close range, most of the guys we'll need to jam will be within 15km of us as they need to get to the gate to jump. And it's mainly the insta guys that are warping right to the gate instead of 15km away, so they will be right on top of us.
