Another log lover. They are near indestructable, they can be left on, they can give a good high with small amounts of cannabis, and they can also do aromatherapy, which means my girlfriend likes them, too. You can use a whip with a log. The draw stems and a dry bubbler are my preference. All of the log vapes are different...I personally am a huge fan of Underdog vapes and Heat Island/Toasty Top as they both can use the same stems, both glass and stainless steel tipped stems. There is a wait depending on what you order from heat island. My favorite is definitely the ss tipped stems for one really thick and milky almost smoke like hit. I have respect for the enano and the woodscents and I would LOVE to try them, I just haven't yet.
I have found that bags are great for parties, but I don't have those experiences anymore. lol Once and a while I use a whip with one of my logs, but just for giggles. I don't really prefer tubing. I don't like cleaning it, I don't like how it smells when it's old. I can't really see the vapor. For those reasons, the fancy systems just don't really work for me. I just give my mom a stem of her choice and some weed and a bag to blow out the stem when done and I grab a stem and we just pass the log back and forth. If I had a bunch of people over it would make sense to have a bag of vapor. But....I would experiment with a vapor lung first. lol
The Plenty is a handheld that isn't designed to be set down while running. You can get a stand for it, or be creative yourself. It's also electronic, so there are many things that can go wrong with it, compared to the very few parts in a log vape. The Plenty has a HUGE bowl and I don't know about you, but I do not like the taste of a bowl that has only been partially vaped. I gotta use it all up in one session or it's just AVB to me. Sometimes I don't want a huge amount of weed. Log vapes have much smaller bowls...some bigger than others, but all tiny when compared to the Plenty. Instead of one giant bowl I pack a couple tiny bowls for myself. One is a session vape, and one is not. You would never dream of loading a new Plenty bowl for every guest. But Everyone gets their own bowl with a log vape. Look up videos of people using both vapes and then imagine you being one of those people. At one point I really really wanted a Plenty...but my tastes have changed and I would no longer want that black and orange thing sitting around my living room. My gf would laugh every time I pulled it out and I would never hear the end of it. lol
There is no right answer. I don't know you or your needs and desires very well, but I hope I made it easier to figure out what model you desire.
