Just bought a set of AM1 Spectrums. These Fins seems great value, just the measurements are bit strange.

Centerfin:
Base 111mm and Depth ~115mm
=> should have 110mm and 112mm //

Sidefins:
Base 112mm and Depth ~115mm
=> should have 116 mm and 115mm

The angel of the centerfin is slightly different like it should be, couldnt measure the angle though. Does someone know whats the deal with that? Are these the new shapes for 2013 and they didnt update the homepage? They look finetuned as hell, but i dont know if keep or send back!
