Recent light curves suggest that the star has approached its (likely)
quiescence around 17.7-18.0. This makes it an increasingly good target
for finding the actual orbital period - still under the assumption that
the not-quite-stable 0.7 day period of 2018 was a superhump (very likely
but not 100% obvious).
So promote that star on your priority list. Unfortunately, the usual
admonition "follow it throughout the night, from tree to tree" doesn't
apply here - because with such an awkwardly long period, it's easy to
get snakebit by extinction effects. Our usual advice of airmass < 2.0
applies... and apart from that, your general quality-of-night opinions
are important too.
I don't have general advice about V versus "wide-V". Obviously V is
better if you can survive the low count rate - but it's a very big price
to pay with a small scope at 18th mag!
Don't forget HP Lib and CR Boo, as well.
