depends on the hopper too unfortunately. The only time that my hopper was able to keep temp and keep with a faster draw was after my first iso soak, besides that short period my unit has never ever been up to par. Let's hope this latest RMA will remedy that
Yeah, I agree, it depends on the hopper. Hopper Labs definitely say that you can pull as hard as you can, and the hopper will keep up. In fairness, mine doesn't seem to be any cooler with a fast pull, it just has a lower-than-ideal maximum temperature.
I got my FC-188 bubbler today, which paired beautifully with my Grasshopper with PFE, I love it. I'm more tempted to send my hopper in for repair now, just to see how amazing I can get it. The vapcap with a vong stem I have definitely beat it by a significant margin in terms of visible vapor production of the same amount of the same material through the bubbler. I want the hopper to match it, really, and judging from videos I've seen online, I'm sure it should be able to manage it.
