Subject: Scope RFI Angled vs Straight, Zoom vs Fixed

Hi Tweeters - I'm considering the purchase of a
high-quality spotting scope for birding, but I'm but
having trouble deciding between an angled (45 degree)
and straight scope, and between a 20-60x zoom and a
fixed 30x or 45x eyepiece. I've been able to "try
out" various setups, but would like to hear opinions
from those who have more experience.

On the zoom vs fixed question, I'm confident that I
can get good optical quality in a zoom, but I'm
concerned that a zoom sacrifices field of view for a
given magnification. (Or I guess for a given field of
view, I could get more magnification with a fixed
eyepiece?)

Any insights would be appreciated, on or off list.
Thanks.
