that is, until you nail down your preferred position and then buy a lighter-weight stem that puts your bars in that position.
Seriously though, having an angle-adjustable stem can be really useful to have around, giving you great adjustability between rides, if you'd like to shift your position a bit. Not a bad idea.
I still just recommend flipping your stem since you said that you wanted to get the bars 1.5 inches higher.
