Jesel is about as good as it gets. They also allow for large diameter springs which the T&D in some cases do not.
I would advise going with pushrod oiling also. I ran spray bar oiling on my engine, and had no trouble. I actually made my own spray bar/lines setup.
If starting from scratch I would have had the Indy Maxx block drilled to allow pushrod oiling. But my machine shop couldnt do it.
The spray bar covers and setup isnt real cheap $400+ so the costs of having the lifter bores drilled should actually save some money. The push rods are Not any more money with the oil holes.

If you are interested in making your own spray bar lines..I wouldnt care to share how I did them
