[c17Lat]

This casting rod has a short handle: http://www.basspro.com/servlet/catalog.TextId?hvarTextId=44303&hvarDept=100&hvarEvent=&hvarClassCode=2&hvarSubCode=6&hvarTarget=browse

while this trigger rod has a long one: http://www.basspro.com/servlet/catalog.TextId?hvarTextId=44304&hvarDept=100&hvarEvent=&hvarClassCode=2&hvarSubCode=6&hvarTarget=browse

I have a trigger rod for my baitcaster, and i never notice the difference in the handles that i see the pros on tv. so, what would make you choose one type of rod over the other, and/or what situations are each used for?

The short 'pistol grip' handles are usually found on shorter rods. You must cast them with one hand. I had a 5'6" rod for pitching under overhanging tree limbs, etc. with a pistol grip.

Longer rods 6' and over will usually have a longer handle for casting with two hands. The longer handle also helps to balance the rod in your hand, so you don't get tired on a long fishing day. I am sure others will add their opinions, but this is how I see it.
