It will depend on the source of the traffic and how that peer follows AS
path into your providers.

What if both annonce my /22 unweighted ?

I know I will loose failover in this scenario.

I am trying to figure out what will happen, traffic will flow inbound
from both in a round-robin like method ?

They are already advertising two /24 for us. So they will advertise a
/22 if I ask them.

Good point on ISP1 Steve, being they are limited already, they might be
just
reselling.

This is assuming that 'ISP1' has the capability to advertise the OP's
route in the first place.

What if ISP1 is simply a customer of another ISP, using PA space, and
just reselling connectivity?

Charles, you really need to find out what others have asked... can the
ISP1 advertise your block of space for you, or do they really mean that
they *can't* do BGP at all.
