After almost 15 years, I am planning on doing a large portrait project in black and white with my 5x7, some enlarged and some contact printed, using both natural light and 5500K fluorescent lights. In preparation, I have bought a Jobo 3006 drum to use with a motor base from my Cibachrome days. I plan on using Ilford HP5 (cost and speed), but am unsure which developer to use.

Due to toxicity I can't use Pyro based developers. For this reason I am leaning towards Xtol, but am a bit concerned about its failures. Are these still a concern? Other suggestions for a developer for use with HP5 and rotary tube are appreciated.
