I am trying to decide between these two mods for my first mechanical. I have read and researched a bit and I understand the sigelei has issues, but it sounds like the 19 b seems somewhat improved. I prefer the looks and bottom firing button of that, but I don't want to be disappointed by its performance. The storm looks decent and seems to be well received but I need someone to talk me out of the 19 b. I will be using an RSST on it that just won't work well with my current set up. (VAMO) I think my VAMO is on the fritz and won't get the coils to fire up and a mechanical seems to be the next step anyway. Please help in this decision!
