drop the xtx200 and go for the xtx50 with ds4 1st, add a second xtx50 and you are golden. cheaper than the xtx200.
Saying that i also respect and like the mk17/g250v.... but i chose the apeks (i sell both)
I agree, for pricing reasons only. The DST/DS4 is heavier, bigger, doesn't breath as well & the hose routing isn't as good, (by a minute amount, unless it's a DST with a 5th port & you're setting up doubles).
