pro37r vs mxl603

[lilcapn]

i've got a pair of pro37rs, use them mainly for overheads, but i don't record drums ALL that often (gotta move too much stuff to set them up...).

i read all about the 603's, both for drums AND acoustic guitars -- are they similar to the pro37r's? more versatile? or just more popular/talked-about because they're such a good deal?

thinking of getting a pair, but don't want to be redundant....

thanks!
