Prodigy v3 - Which Atty Adapter?

[Knowone]

I'll probably have other questions, but this is the question that's at the front of my mind at this moment.

What are the differences between the possible atty attachments for the Prodigy v3?

Here's the list of attys that fit between the 3 different adapters:
510/801/4072/BE112/901/4075/KR808

I'm looking for versatility. I'm still very new to PVs, and I only found out that I can drip with my RN4072 last night. So far, I like dripping more than using the cart. But, I'm still not sure what I'll settle on in the end. Since I don't have a collection of attys built up, I can choose any of the adapters as I'll be buying attys to use with whichever I choose. I'd like the ability to try regular attys and cartos, low and high resistances with lower and higher voltages, etc...

I'm a big proponent of function over form, so this isn't very important if longer attys have a significant advantage over shorter ones, but I'd rather that the atty be short than long.

Also, (not a prodigy-specific question) do all cartomizers have a style where one must fill them with a syringe? Or, are some open-ended? If they are all syringe-filled, does that mean that dripping is exclusively done with regular attys without using cartridges? If this is true, what is the advantage of using a carto?

Thanks much for any suggestions and/or clarification!

id get it with the 510 adapter. I use 510 mainly and have a few mods that use 808 but there are adapters to go between the 2. Basically an 808 and a 510 are the same just one has female threads and the other male. Plus in my opinion those are the 2 most used conections. Also if your gonna use cartos i would definately get a 510 and buy some quality cartomisers, they also come in 808 from Vapor4life or other vendors but like i said if you go with a 510 or 808 i dont think you can go wrong especially if you buy an adapter from a diy suplier like mad vapes.

Any other opinions? I saw someone recommending the 901 too.

Also, what about the carto question? Must you always fill them with a syringe? Is all dripping done with an open-ended atty?

Is the point of a carto that it can hold more liquid at a time than an atty with a cart?
