Hahahaha... Sandman, for equality's sake... Remember, personal preference rules all, above and beyond... The 1.5 is the most commonly flown Rev in the US, and probably 80% of the fliers have knots on both top and bottom.
I've been on Revs for 14 years, flown all types, and have bagged my share of championships in quadline... "My way" isn't necessarily the right way, but it works well and is time-tested.
