I haven't run into any trouble with 15.1 on 7200 yet, but I've found 15.x
(both M and T images) to be a bagful of fun on smaller ISRs.  In fact, I
had an emergency upgrade on a T image today, due to BVI on one interface
knocking out ipv6 ND on a completely separate interface.  Nice.

Unless you have any particular reason to go to 15.1, I would recommend
using a recent SRE image.
