After a couple of months using the Vision Spinner I was ready to take off the "training wheels" and upgrade. I looked and researched a lot and decided on the iTaste VTR, it's a fantastic mod!! I love the size, the weight, the way it fits my hand, pocket friendly, the VV/VW adjustments, the battery life, I love everything about it EXCEPT.........the way it vapes. With my Vision Spinner @ 4.5v-4.8v, BCC Mega tank, bottom feed clearo with a 2.5ohm single coil, 100% VG 18mg juice I got a really good chest hit, almost to the point you feel like your going to cough a little. Now that I've switched out the Spinner for the VTR I don't get that chest hit I love. The tank, coil, voltage, and juice has all stayed the same I just switched out the the main body. I've tried adjusting the voltage and the wattage but I've had no luck getting it to hit me in the chest like my Spinner did. Any ideas on what I can change in order to get that chest hit back? If I can't get it figured out, watch Craigslist or eBay for an almost brand new iTaste VTR for sale!!
