5L works well if u check the records, but it is hard to invest..the tech you learned and you familiar in 4L like CVCV or CVVC or repeat letters or abbreviation, not really work while choose 5LοΌimo, the beauty of 5L is hard to capture , I believe lots related with its rhythm and feeling...so, actually, I really suggest avoid invest 5L until you are a true Pro in branding and Language...my 2 cents...
