I wouldn't bother with 1. It was interesting to see one with such high speed but other than that, it wasn't fantastic.
As for 2 .... it's not bad. But you could find better. If you are serious about going VERY high level (like, 200+), you want implacable (it's pretty much essential if you want to actually hit any of the agility monsters at that level!) and an anti-pet skill (hypno, cry of the damned) is not absolutely essential ..... but it ain't far off it!
If you don't plan on taking them that high, you'd need to re-evaluate them at lower levels ... ie. the level you realistically think they might reach.
