Excellent choice. I have a Drag and enjoy it very much. A bit heavy, but that comes from the solid materials used. Going back to your original thoughts, I have a suggestion you might like.
Here is how I reasoned spending the money for that Triade you were interested in (Lost Vape is worth keeping in your radar). My last cigarette was a Marlboro 27 in August of 2015. I started with a Juul , moved to the Innokin CoolFire IV TC100 (a great internal battery mod) followed by a T-Priv by month 24. I was just about ready to reward myself for successfully transitioning. I DECIDED 27 MONTHS AFTER MY LAST Marlboro 27 WAS MY SPECIAL OCCASION MOMENT- WHEN DO YOU THINK YOURS SHOULD BE?
I placed an order for the Modefined Prism 250watt, which you were curious about & then found a great deal on a Lost Vape Triade DNA 250 at ejuices.com… well below any I had seen to date, I grabbed it. Both arrived by the second week of November. I find them to be relatively equal in my vape experience except for the escribe software from evolv & the $ difference. I also bought a Geekvape Aegis the month before simply because of its military spec rating.
I would suggest you order a Prism now as a “back-up” mod. They are about $50 (gearbest has all the color combinations… go for the elephant black battery door, you will like it). The DNA 250c will be released soon so hold off on a Triade. Modefinded already offers the one big thing the Triade will be getting soon, a 3rd button (menu) which saves you from dealing with those complicated button combinations. 3 battery mods will last longer between charges. The Prism weighs 30grams more than the Drag with batteries in it. The Triade is another 30grams heavier. Both feel great in the hand & are really accurate in output.
The Aegis another option for a backup mod for a few reasons. You only vape 40-50 watts, so its 100 watt power is enough. The vape experience is closer to the ProColor you know, but not as good as the Drag’s. It’s my goto mod for bad weather days. I don’t feel comfortable vaping in the rain with any other mod. The battery life is decent with a 26650, but not what you get from 2 18650s. Feels great in the hand & has a display that is very clear. The Drag display is similar to a Triade’s in size, I’m sure you have noticed that difference from the ProColor.
Final points. Are you a Windows or Mac person. Make sure you buy mods that you can upgrade with your computer. I had to use my brother’s to do my Drag update. Also, in these posts I didn’t see anything final on how you charge your batteries. I like the Nitecore I4. I have a buddy who just made the switch a week ago and he asked me to choose his gear. I got him the iCare2 to start and a Thinkvape Finder 75c along with a Nautilus2 & Siren2 tanks plus the I4 charger. The Finder 75c really impressed me & is that Therion style you were originally leaning toward. It is more expensive than the Drag or the Prism, but if you find yourself still vaping under 50 watts, a DNA 75c dual battery is enough and perhaps 40 or 50 grams lighter than the Drag.
Hope you had a nice vape while reading this, and while you don’t need as many mods as I bought in 2017, having another quality mod around is helpful. The cheaper option is to buy spare batteries and swap them in while the others are charging. VTC5a, VTC6 & Samsung 25r’s do me well. The VTC6a is about to hit the market and Mooch is impressed with them.
Be well. Phil
