[VHFcontesting] one band for UHF contest

[Pete Kobak via VHFcontesting]

Newbie to contesting. Had a baby rover in the July CQ contest and it was a lot of fun. Looking forward to the Sept. ARRL VHF contest.
 
Question on the August UHF contest this weekend: I only have one UHF band on my radio (70cm), and no beam yet. Was planning on getting the beam and associated equipment for the Sept. VHF contest, but is it worth it to accelerate my 70cm capability for this coming weekend? I assume most everyone in the UHF contest has many bands; would it be a waste of time for those I contact to only have the one band? I probably would not be a traveling rover, just operate from a single good location for a limited period of time.
 
Note that I'm not talking about being competitive in the contest, it's just fun making multiple contacts on "weak signal" bands that don't normally have much activity. My main concern is that I don't want to annoy the competitive contesters.
 
Thanks!
