Gaining

Has anybody noticed a big difference between using a funnel/not? Does drinking a (most likely melted ice cream or gainer shake) lot in a short period help? Or is funnel feeding more of something that you do just for the sheer gluttony?

What about stomach stretching, would not the funnel be good for this? To push the feedee past full, and increasing the amount needed to feel full?
I would think the effecta of the funnel would last well past the feeding.

I've tend to find that you can bypass a lot of the problems that arise when drinking with a funnel, for instance

Mouth getting too cold ( brainfreeze )
Swallowing
Air ( depending on how the funnel is being used the drinker can just plug the hole, or just be forced to drink it all before taking a breath )
Stomach Capacity

For whatever reason, I find I can chug more when funneling, but that's me

I'm thinking about giving it a shot, does anyone have any tips? I would be doing this alone, if that makes a difference.
