I love hills too, Mim. I find flat and fast too boring. That route you have mapped out will have plenty of climb for you. The High Peterskill Trail is great.
I do not have my maps handy but there is a good hill leading up from Rhododendron Bridge heading towards Skytop that I have used for hill repeats. Laurel Hill, maybe?
Lenape Lane is also a good long climb.
