[CQ-Contest] Feeding an 80m Delta Loop

I'm using a delta loop with the apex at 77'.  I'm currently feeding it 
in the middle on the bottom horizontal leg (which is 10' above the 
ground) with a 2:1 balun.

Works just great at my qth.

I do plan on moving the feed point to a 1/4 down from the top on one of 
the vertical legs.  I also plan on installing stubs in the two lower 
corners with relays so I can switch between cw ssb.

I know the velocity factor is 0.82, so I will take that into account. A couple of comments suggested that a delta loop is a major disappointment as compared to other antennas. The only other antenna that I have is an 80m vee at 100feet. Am I going to waste my time? The apex will be at 90feet.
