Changing to Pay to Pledge... Thoughts?

So... I was thinking of changing my Patreon page to pay to pledge. What that means is that when someone pledges, they have to immediately make a payment before they can join. However, I am not sure exactly how or if  this would affect existing Patreons. I am going to do a little research into that...

Anyway, the reason I am thinking of doing that is because I notice a lot of people pledging then deleting their pledge like 30 minutes later. Which is annoying and seems a little unfair if they are just looking at stuff then leaving.

Is this a good idea or a bad idea? I am not familiar with Pay to Pledge but if I can get it, I think it might be good to use.
