Which Vise-Grip pliers are the most useful?

[visionguru]

I'd like to add a vise grip to my tool box, but not sure which is the most useful one.
Size: 10", 7", 5"
Style: Curved, straight, long nose.

Opinions?

all of them are useful, but the 5 inch ones get the most use around here.

5" gets my vote cuz its the only one i have...

I tend to like the larger ones for more leverage

If I could only have one I'd take the 10" curved.

[Ludi Mali]

if you have another set of pliers in your toolbox you can go with the smaller set and then use the bigger ones on the handle for the extra leverage

I'm definitely gonna say the 7" curved are the best. I have all three and I definitely use the 7 the most.

yeah i agree. i think the 7" works best. vise grips aren't the tool of choice in a tight spot, so you might as well have a bit more leverage! :)
