In reply to joe.91:
Those which you have mentioned are good. Syrett's doesn't really feel like a highball to be honest. The Hovis problems are excellent intro highballs as they take you to a height that you really mustn't fall off from, but the hard climbing is all very close to the floor.
Psycho is not quite an "introductory" slab climb but the difficulty is only about 6B+. As a friend said to me before I did it "you won't fall off it, you might lose your nerve and jump off though". Rabbits Paw and Angel's Wall are both classics but also very easy.
Great Wolfrey is staggering but the climbs there are hard and, although the tops of the climbs are generally easier, they are also of a height where falling off is not to be advised. In Memoriam is good and very soft at the grade (E4 6a for a trad solo we thought. Font 6B/+ with a non-falloffable few top moves with a few pads). There are only a few climbs at Wolfrey that work well as highballs that are sub 7A. Walter's Rib is exceptional. A little vid of a few things here:
The three that Robert mentions at Back Brimham are very good and none are too taxing or overly high.
The best easy highball in Yorkshire (in my book) is Make My Heart Fly at Yeadon crag. Its only about 5+/6A but the crux is right at the top and I still find it a pant filler despite having done it several times. You can also test your mettle against The Cestrian (7A+) which isn't very high but has the crux at the top, and the as yet unrepeated The Arkenstone (7A+/maybe 7B?) which has the crux at the bottom. Guide is here:

Plenty at Brimham (which I haven't done) like Successor State and Ritornal.
As mentioned, Poetry in Motion and the White Doe are excellent. Don't neglect Ghost Road which is equally worthy of attention and if you're going well and feel confident on slabs and have a few pads in tow then Verge of Tranquility is quite out there (6C+ frictiony slab climbing/E5 6b).
And if you get all of those done then you are going well!
