IH kind of feels like cheating to me. That is my personal opinion and I don't judge.
There are, however, two reasons I will someday break down and get one.
The first reason is that Dyna usage in the cold sucks. I have to keep everything in the garage where it's been 45f all the time lately. Butane torches do not work well in those temperatures! Every time I go to heat a cap, halfway before the click, the flame will peter out. Ill grab another torch and same thing. Half the time, like a dummy, I think "it's out of fuel", so I go to put some in and it sprays all over the place, because of course, it's actually full. So if I want to use Dyna I have to make sure I have a torch in the house. And that rarely works out in my favor. To make matters worse, all my favorite vapes are butane.
The other reason is purely for the hedonistic pleasure of loading up like 10 caps and just ripping them all in succession. Just fill the room with glorious vapor! You cant do that with a torch unless you have a Dyna pit crew of at least two and they would need a lot of practice to match the consistency of an IH. So unless you have a couple of unemployed friends, IH is the ticket to that ride.
In the end I'm sure I'll succumb. I think I'll just wait until the very, very end. Like my neighbor who still doesn't have a smart phone. You know, the longest you could possibly wait before buying an IH. I'll just wait until Dynavap puts theirs out.
