i dun need to check, i'm in the 'Know', and a subscriber of the newsletter.
i agree with the fact that those with Harp fly at 12.65498408973247 km/hr SLower than those with Triangles, cos i also read that in the March 06 issue of Heavenly Weekly, but dun forget that in Dec 06 issue, the Heaven Committee for Better Heavenly Muscial Thingy Stuff came out to admit that the Harp projects more Grace.
Grace is more important than Speed, remember?
as for maintenance, the Harp is also rated as the Best becos the tough cleaning provides fun-filled activities for the Heavenites...
