Careful there! Remember, I did THREE extra shots in all mine and that was TOO MUCH. Go for two and see how that works! I'd be interested to know, so I have a baseline for my next order with them.
I usually go with two, yeah. Even two is too much for some flavors; next time I get Root Beer, I'm going with none. I got it with one shot and it's fantastic but it'll burn out my tongue within an hour. Same goes for Pumpkin Spice, one shot is how I prefer it but even that might be too much for most.
Often, figuring out how many shots you like is a flavor by flavor thing only accomplished with trial and error. Two shots for most fruits has worked well for me so far, so I'm not worried about trying two shots with lime - it'd also get plenty of steep time since I have 60ml of lime from the aforementioned other vendor... plus I'm finally at the point where each monthly order is actually for whatever I want to vape a month *from* now.
Anyway, we'll see. It depends on what my check looks like this month, cause stockpiling my ADVs is still my first priority.

I'll definitely post here if I sneak some lime +2 in though.
