Re: InnoDB to MyISAM
This might have the answer:

A word of caution on Engine changing: Indexes have some subtle differences.
InnoDB's PRIMARY KEY is "clustered"; MyISAM's is not.
InnoDB's Secondary keys have to drill down the primary key; MyISAM does not.
InnoDB's secondary indexes have the PK implicitly in the leaf nodes in the index; this may lead to InnoDB "Using index". MyISAM does not.
MyISAM does not require a PK.
