yes, always check your connection and clean as needed. i use a reo which is a bottomfeeder so i dont worry, it has a catch cup in case i squeeze too much juice up. it also helps to remove and blow out your atty from the connection end about once a day or so or if changing juices. i love the 357 too but you cant go wrong with the cisco attys, i used the 306s most of the time with a cannon drip tip. the cannon and other 306 tips slide over your 306 atty where the 510 use the tips you fit inside the atty. there are many different styles and price levels. i use trippy tips but they are expensive and pretty hard to get but i seem to get better flavor with them than with delrin or plastic. there are also places to get cheaper glass drip tips than the trippys if its not in your budget to spend 25 for a tip.
as with everyone else, i too am always looking for the next greatest atty so its a never ending search,lol. if i was just starting out there is no way id go for a 357, just too expensive to fry one out of the gate and be out the cash. you have to learn them and they are a different animal in the way you hit them. as far as i know they are the only atty that has a built in catch cup to hold extra juice and you need to make double sure they stay very wet with juice.
