@CA99, I was thinking of the Lightning/Pirahna/Blazer when I drew that, hence a similarly shaped handle. Either one can be comfortable, but typically the open ones are better, yes. I'll keep that in mind for the remainder of my dude-ish lineup. As for intake tubes, I've never been a fan, I always prefer intake holes at the bottom of the reservoir.
@atvan, I find semi-tracked pumps tend to be smoother, hence my tendency toward them. It's just a matter of preference (good question for a poll, no?)
Anyway, as promised, more installments. This is the XP100something series' newborn child. I'm contemplating whether the reservoir could be reduced in size to get the required 2 PCs. It features an open handle, 2 nozzles (as I said in the "Want better water blasters? Wish Here!" thread, I want riot blasts to become standard), and is very compact. However, it does have a free pump that will rub up against the bottom of the firing area.
I got lazy with the drawing, but it works just as well I think. Let's call this one Roarcreature. I guess that means the lineup will be called the Roar Line.
