I would preferably try to do some MEA or MAA (the amphetamines analogues of MEPEA and MAPEA, see http://www.erowid.org/library/books_online/pihkal/pihkal123.shtml (http://www.erowid.org/library/books_online/pihkal/pihkal123.shtml)
)
4-allyloxy-3-methoxy-amphetamine look most interesting to me than the 4-methoxy counterpart.
As a side note, it seem than MMA (3-methoxy-4-methyl-amphetamine) was distributed in Italia. Shulgin told in pihkal#123 that it is apparently 'quite disphoric' :( .
But I dont take that report from the italian forensics too seriously.
Let's taste all those promising compounds! ;D
